Abstract: Nitrogen-rich graphene nanosheets (NGN) with intentionally crumpled, stacked, and cross-linked sheet structures were developed using hydrothermal and/or formaldehyde polymerization processes. It is revealed that the hydrothermal treatment produced crumpled NGN (6.0 at% N) with a high surface area of 383 m(2)·g(-1). In contrast, the formaldehyde polymerization process yielded stacked NGN (11.3 at% N) with very low surface area. The combination of formaldehyde polymerization synthesis with hydrothermal treatment led to NGN (14.7 at% N) with a cross-linked structure and a moderate surface area of 88 m(2)·g(-1). Interestingly, this cross-linked NGN exhibited the best electrochemical performance compared with other NGN, with a remarkable specific capacitance of 201 F·g(-1) at 0.05 A·g(-1) in 1 M H2SO4 electrolyte, and an excellent retention rate of 96.2% of the initial capacitance after 10 000 charge-discharge cycles at a current density of 5 A·g(-1) was achieved.

Abstract: Organic carbon aerogels (CAs) were prepared by a sol-gel method from polymerisation of resorcinol, furfural, and hexamethylenetetramine catalysed by KOH at around pH 9 using ambient pressure drying. The effect of KOH in the sol-gel on CA synthesis was studied. It was found that addition of KOH prior to the sol-gel polymerisation process improved thermal stability of the gel, prevented the crystallinity of the gel to graphite, increased the microporosity of CA and promoted activation of CA. The CAs prepared using the KOH catalyst exhibited higher porosity than uncatalysed prepared s les. Activation in CO(2) at higher temperature also enhanced the porosity of CAs. Adsorption tests indicated that the CAs were effective for both basic and acid dye adsorption and the adsorption increased with increasing surface area and pore volume. The kinetic adsorption of dyes was diffusion control and could be described by the second-order kinetic model. The equilibrium adsorption of dyes was higher than activated carbon.

Abstract: Introducing CO2 electrochemical conversion technology to the iron-making blast furnace not only reduces CO2 emissions, but also produces H2 as a byproduct that can be used as an auxiliary reductant to further decrease carbon consumption and emissions. With adequate H2 supply to the blast furnace, the injection of H2 is limited because of the disadvantageous thermodynamic characteristics of the H2 reduction reaction in the blast furnace. This paper presents thermodynamic analysis of H2 behaviour at different stages with the thermal requirement consideration of an iron-making blast furnace. The effect of injecting CO2 lean top gas and CO2 conversion products H2–CO gas through the raceway and/or shaft tuyeres are investigated under different operating conditions. H2 utilisation efficiency and corresponding injection volume are studied by considering different reduction stages. The relationship between H2 injection and coke rate is established. Injecting 7.9–10.9 m3/tHM of H2 saved 1 kg/tHM coke rate, depending on injection position. Compared with the traditional blast furnace, injecting 80 m3/tHM of H2 with a medium oxygen enrichment rate (9%) and integrating CO2 capture and conversion reduces CO2 emissions from 534 to 278 m3/tHM. However, increasing the hydrogen injection amount causes this iron-making process to consume more energy than a traditional blast furnace does.

Abstract: The effect of chemical treatment on the capacitance of carbon electrodes prepared from waste coffee grounds was investigated. Coffee grounds were impregnated with FeCl 3 and MgCl 2 and then treated at 900 °C. The resultant carbons were compared with activated coffee ground carbons prepared by ZnCl 2 treatment. The carbon treatment processes of FeCl 3 and MgCl 2 were studied using thermal gravimetric analysis. Raman spectroscopy, x-ray photoelectron spectroscopy, and N 2 and CO 2 adsorption were used to characterize the activated carbons. Activation with ZnCl 2 and FeCl 3 produced carbons with higher surface areas (977 and 846 m 2 /g, respectively) than treatment with MgCl 2 (123 m 2 /g). Electrochemical double-layer capacitances of the carbons were evaluated in 1 M H 2 SO 4 using two-electrode cells. The system with FeCl 3 -treated carbon electrodes provided a specific cell capacitance of 57 F/g.

Abstract: Amorphous nickel carbonate particles are catalysts for the oxygen evolution reaction (OER), which plays a critical role in the electrochemical splitting of water. The amorphous nickel carbonate particles can be prepared at a temperature as low as 60 °C by an evaporation-induced precipitation (EIP) method. The products feature hierarchical pore structures. The mass-normalized activity of the catalysts, measured at an overpotential of 0.35 V, was 55.1 A g(-1) , with a Tafel slope of only 60 mV dec(-1) . This catalytic activity is superior to the performance of crystalline NiOx particles and β-Ni(OH)2 particles, and compares favorably to state-of-the-art RuO2 catalysts. The activity of the amorphous nickel carbonate is remarkably stable during a 10 000 s chrono erometry test. Further optimization of synthesis parameters reveals that the amorphous structure can be tuned by adjusting the H2 O/Ni ratio in the precursor mixture. These results suggest the potential application of easily prepared hierarchical basic nickel carbonate particles as cheap and robust OER catalysts with high activity.

Abstract: Interactions of electrolyte ions at electrocatalyst surfaces influence the selectivity of electrochemical CO 2 reduction (CO 2 R) to chemical feedstocks like CO. We investigated the effects of anion type in aqueous choline halide solutions (ChCl, ChBr, and ChI) on the selectivity of CO 2 R to CO over an Ag foil cathode. Using an H‐type cell, we observed that halide‐specific adsorption at the Ag surface limits CO faradaic efficiency (FE CO ) at potentials more positive than −1.0 V vs. reversible hydrogen electrode (RHE). At these conditions, FE CO increased from I − Br − Cl − , that is, in the opposite order to the strength of specific adsorption of the halide ions (Cl − Br − I − ). At potentials of −1.0 to −1.3 V vs. RHE, restructuring of the Ag surface in ChI and ChCl via dissolution and re‐electrodeposition led to more CO‐selective Ag facets ([220], [311], and [222]) than in ChBr. This mechanism allowed very high faradaic efficiencies for CO of 97±2 % in ChI and 94±2 % in ChCl to be achieved simultaneously with high current densities at −1.3 V vs. RHE. We also demonstrate that high selectivity to CO (FE CO %) in ChCl (at −0.75±0.06 Vvs. RHE) and ChI (at −0.78±0.17 V vs. RHE) could be achieved at a current density of 150 mA cm −2 in a continuous flow‐cell electrolyser with Ag nanoparticles on a commercial gas diffusion electrode. This study provides new insights to understand the interactions of anions with catalysts and offers a new method to modify electrocatalyst surfaces.

Abstract: The co-doping of heteroatoms has been regarded as a promising approach to improve the energy-storage performance of graphene-based materials because of the synergetic effect of the heteroatom dopants. In this work, a single precursor melamine phosphate was used for the first time to synthesise nitrogen hosphorus co-doped graphene (N/P-G) monoliths by a facile hydrothermal method. The nitrogen contents of 4.27-6.58 at% and phosphorus levels of 1.03-3.00 at% could be controlled by tuning the mass ratio of melamine phosphate to graphene oxide in the precursors. The N/P-G monoliths exhibited excellent electrochemical performances as electrodes for supercapacitors with a high specific capacitance of 183 F g(-1) at a current density of 0.05 A g(-1), good rate performance and excellent cycling performance. Additionally, the N/P-G electrode was stable at 1.6 V in 1 m H2 SO4 aqueous electrolyte and delivered a high energy density of 11.33 Wh kg(-1) at 1.6 V.

Abstract: Electrochemical CO 2 reduction (CO 2 R) could potentially be used with electricity from renewable sources to convert CO 2 into various products such as CO, formic acid (HCOOH), methane (CH 4 ), ethylene (C 2 H 6 ), etc. The overall efficiency of the CO 2 R process is largely linked to the catalyst on which CO 2 is being reduced. However, the local environment surrounding the catalyst is generally subjected to reaction-driven changes during CO 2 R which play a significant role in affecting the overall efficiency, product selectivity, and reaction rate. Therefore, the understanding of catalyst-electrolyte interactions during CO 2 R could be effective in further improving the performance of the catalyst. For ex le, the potential buffering effects of different alkali cations at the catalyst surface due to variations in cation hydrolysis can influence the local proton concentration and thus CO 2 R. 1 The surface tethering of catalyst surface with functional additives such as glycine 2 , poly(acrylamine) 3 , thiol group 4 , etc. have been shown to improve product selectivity by affecting the binding strength with CO 2 R intermediates. In our recent work 5 , we uncovered that the interactions between a polycrystalline Ag foil and reline solution including (i) in-situ nano-structuring of Ag foil by electrodeposition of dissolute native Ag oxide layer, (ii) HER suppression by specifically adsorbed choline ions which restrict the protons availability at the interface, and (iii) stabilization of CO 2 R intermediates by hydrogen bonding with amino group of urea led to a remarkable CO selectivity of (96±8)% at - 0.884 V vs. RHE. Anions of the electrolyte especially halide ions (Cl - , Br - , and I - ) have been reported to affect both the selectivity and activity of CO 2 R. 6, 7 Specifically adsorbed halide ions can modulate the coverage of adsorbed CO on the catalyst surface by stabilizing the intermediates. 8 Moreover, halide ions can induce morphological changes of the catalyst surface during CO 2 R which have demonstrated to enhance the selectivity of CO over Ag catalysts. 9 Inspired by the effect of halide ions, we are investigating the role of different halide ions such as Cl - , Br - and I - in choline based electrolytes over Ag foil for CO 2 R. Our initial experiments have shown that at less negative potentials (between – 1.0 to – 0.7 V vs RHE), I - exhibited the lowest selectivity for CO, and we attribute this result to I - having the highest specific adsorption at the Ag surface and adsorbed I - may restrict the active sites for CO 2 R. However, at larger negative potentials the electrostatic repulsion between the Ag surface and specifically halide ions increases causing the interactions of the catalyst-halide ions to be weakened and thus improving the CO selectivity. SEM characterization of the Ag foil after CO 2 R has confirmed the change in morphology of the Ag surface (more-rougher). Moreover, we performed several flow-cell CO 2 R experiments over Ag-based gas diffusion electrodes (GDEs) and could achieve a CO selectivity over 90% at 150 mA·cm -2 in all three electrolytes. Therefore, altering the interactions between the Ag catalyst and choline-based halide ions during CO 2 R could be a potential approach to enhance the catalytic activity of Ag-metal or Ag nanoparticles.
