Abstract: Ultrathin metal-organic framework (MOF) nanosheets (NSs) offer potential for many applications, but the synthetic strategies are largely limited to top-down, low-yield exfoliation methods. Herein, Ni-M-MOF (M=Fe, Al, Co, Mn, Zn, and Cd) NSs are reported with a thickness of only several atomic layers, prepared by a large-scale, bottom-up solvothermal method. The solvent mixture of N,N-dimethylacetamide and water plays key role in controlling the formation of these two-dimensional MOF NSs. The MOF NSs can be directly used as efficient electrocatalysts for the oxygen evolution reaction, in which the Ni-Fe-MOF NSs deliver a current density of 10 mA cm

Abstract: The electrochemical urea oxidation reaction (UOR) is an alternative to electrooxidation of water for energy–saving hydrogen (H 2 ) production. To maximize this purpose, design of catalysts for selective urea‐to‐nitrite (NO 2 – ) electrooxidation with increased electron transfer and high current is practically important. Herein, a cobalt, germanium (Co, Ge) co‐doped nickel (Ni) oxyhydroxide catalyst is reported first time that directs urea‐to‐NO 2 – conversion with a significant Faradaic efficiency of 84.9% at 1.4 V versus reversible hydrogen electrode and significantly boosts UOR activity to 448.0 mA cm −2 . Importantly, this performance is greater than for most reported Ni‐based catalysts. Based on judiciously combined synchrotron‐based measurement, in situ spectroscopy and density functional theoretical computation, significantly boosted urea‐to‐NO 2 – production results from Co, Ge co‐doping is demonstrated that optimizes electronic structure of Ni sites in which urea adsorption is altered as NO‐terminal configuration to facilitate CN cleavage for *NH formation, and thereby expedites pathway for urea to NO 2 – conversion. Findings highlight the importance of tuning intermediate adsorption behavior for design of high‐performance UOR electrocatalysts, and will be of practical benefit to a range of researchers and manufacturers in replacing conventional water electrooxidation with UOR for energy‐saving H 2 production.

Abstract: Electroreduction of carbon dioxide (CO 2 ) into multicarbon products provides possibility of large-scale chemicals production and is therefore of significant research and commercial interest. However, the production efficiency for ethanol (EtOH), a significant chemical feedstock, is impractically low because of limited selectivity, especially under high current operation. Here we report a new silver–modified copper–oxide catalyst (dCu 2 O/Ag 2.3% ) that exhibits a significant Faradaic efficiency of 40.8% and energy efficiency of 22.3% for boosted EtOH production. Importantly, it achieves CO 2 –to–ethanol conversion under high current operation with partial current density of 326.4 mA cm −2 at −0.87 V vs reversible hydrogen electrode to rank highly significantly amongst reported Cu–based catalysts. Based on in situ spectra studies we show that significantly boosted production results from tailored introduction of Ag to optimize the coordinated number and oxide state of surface Cu sites, in which the * CO adsorption is steered as both atop and bridge configuration to trigger asymmetric C–C coupling for stablization of EtOH intermediates.

Abstract: Obtaining partial methane oxidation reaction (MOR) with various oxygenates via a mild electrochemical method is practically difficult because of activation of stable C─H bond and consequent reaction pathway regulation. Here, a real‐time tandem MOR with cascaded plasma and electrocatalysis to activate and convert the methane (CH 4 ) synergistically is reported for the first time. Boosted CH 4 conversion is demonstrated toward value‐added products including, alcohols, carboxylates, and ketone via use of commercial Pd‐based electrocatalysts. Compared with hash industrial processes, a mild condition, that is, anode potential 1.0 V versus RHE (reversible hydrogen electrode) is used that mitigates overoxidation of oxygenates and obviates competing reaction(s). One evidence that Pd(II) sites and surface adsorbed hydroxyls are important in facilitating activated‐CH 4 species conversion, and establish a reaction mechanism for conversion(s) that involves coupling reactions between adsorbed hydroxyls, carbon monoxide and C 1 /C 2 alkyls. One conclude that pre‐activation is important in boosting electrochemical partial MOR under mild conditions and will be of benefit in the development of sustainable CH 4 conversion technology.

Abstract: Aqueous Zn‐Iodine (I 2 ) batteries are attractive for large‐scale energy storage. However, drawbacks include, Zn dendrites, hydrogen evolution reaction (HER), corrosion and, cathode “shuttle” of polyiodines. Here we report a class of N‐containing heterocyclic compounds as organic pH buffers to obviate these. We evidence that addition of pyridine /imidazole regulates electrolyte pH, and inhibits HER and anode corrosion. In addition, pyridine and imidazole preferentially absorb on Zn metal, regulating non‐dendritic Zn plating /stripping, and achieving a high Coulombic efficiency of 99.6 % and long‐term cycling stability of 3200 h at 2 mA cm −2 , 2 mAh cm −2 . It is also confirmed that pyridine inhibits polyiodines shuttling and boosts conversion kinetics for I − /I 2 . As a result, the Zn‐I 2 full battery exhibits long cycle stability of 000 cycles and high specific capacity of 105.5 mAh g −1 at 10 A g −1 . We conclude organic pH buffer engineering is practical for dendrite‐free and shuttle‐free Zn‐I 2 batteries.
