Exceptional Photocatalytic Hydrogen Peroxide Production from Sandwich‐Structured Graphene Interlayered Phenolic Resins Nanosheets with Mesoporous Channels
Publisher: Wiley
Date: 26-02-2023
Abstract: Harnessing solar energy to produce hydrogen peroxide (H 2 O 2 ) from water (H 2 O) and dioxygen (O 2 ) via artificial photosynthesis is an attractive route. To achieve high solar‐to‐H 2 O 2 conversion efficiency, herein, an interfacial self‐assembly strategy is adopted to pattern mesoporous resorcinol‐formaldehyde resin (MRF) onto reduced graphene oxide (rGO) to form sandwich‐structured rGO@MRF polymeric photocatalysts. The internal graphene layer that mimics the electron transport chain of plant leaf, can effectively transfer electrons, and promote the two‐electron reduction of O 2 . Moreover, the mesoporous channels mimic the stomata, beneficially boost the fluid velocity, enrichment of O 2 , and diffusion of H 2 O 2 . Consequently, the developed metal‐free material can achieve an exceptional solar‐to‐chemical energy conversion efficiency of 1.23%. This ingenious interface engineering brings new opportunities for the design of efficient artificial photocatalysts.
Scalable high yield exfoliation for monolayer nanosheets
Publisher: Springer Science and Business Media LLC
Date: 16-01-2023
DOI: 10.1038/S41467-022-35569-8
Abstract: Although two-dimensional (2D) materials have grown into an extended family that accommodates hundreds of members and have demonstrated promising advantages in many fields, their practical applications are still hindered by the lack of scalable high-yield production of monolayer products. Here, we show that scalable production of monolayer nanosheets can be achieved by a facile ball-milling exfoliation method with the assistance of viscous polyethyleneimine (PEI) liquid. As a demonstration, graphite is effectively exfoliated into graphene nanosheets, achieving a high monolayer percentage of 97.9% at a yield of 78.3%. The universality of this technique is also proven by successfully exfoliating other types of representative layered materials with different structures, such as carbon nitride, covalent organic framework, zeolitic imidazolate framework and hexagonal boron nitride. This scalable exfoliation technique for monolayer nanosheets could catalyze the synthesis and industrialization of 2D nanosheet materials.

Highly recoverable TiO2–GO nanocomposites for stormwater disinfection
Publisher: Elsevier BV
Date: 05-2016
DOI: 10.1016/J.WATRES.2016.02.067
Abstract: A highly recoverable titanium dioxide-graphene oxide (TiO2-GO) composite was developed by a facile method of ultrasonic treatment of GO nanosheets and TiO2 nanoparticles, which should overcome the separation problem of nanosized TiO2 from treated water. Separability of the prepared s les was systematically investigated by gravity settling experiments. The s les' photocatalytic activity for stormwater disinfection was also studied under the irradiation of a solar simulator. The results demonstrated that TiO2-GO showed high efficient separability due to its accelerated settling behaviour. Zeta-potential analysis showed that the accelerated sedimentation of the catalyst was attributed to the aggregation of TiO2-GO resulting from the electrostatic attraction between TiO2 and GO. The TiO2-GO composite with a mass ratio of 100:2 (TiO2-2%GO) achieved both higher separability and good photocatalytic activity for stormwater disinfection. Its suspension became clear (turbidity < 50 NTU) after 8 h of sedimentation, while 99.5% of E.coli were deactivated in 90 min. The TiO2-GO composite exhibited excellent durability no apparent change in the separability of TiO2-2%GO was observed after 10 treatment cycles (15 h in total), while only slight decrease in the photocatalytic activity was noted. In conclusion, the developed TiO2-GO composite showed promising results for stormwater disinfection.

Production of Hydrogen Peroxide by Photocatalytic Processes
Publisher: Wiley
Date: 18-05-2020
Abstract: Hydrogen peroxide (H 2 O 2 ) has received increasing attention because it is not only a mild and environmentally friendly oxidant for organic synthesis and environmental remediation but also a promising new liquid fuel. The production of H 2 O 2 by photocatalysis is a sustainable process, since it uses water and oxygen as the source materials and solar light as the energy. Encouraging processes have been developed in the last decade for the photocatalytic production of H 2 O 2 . In this Review we summarize research progress in the development of processes for the photocatalytic production of H 2 O 2 . After a brief introduction emphasizing the superiorities of the photocatalytic generation of H 2 O 2 , the basic principles of establishing an efficient photocatalytic system for generating H 2 O 2 are discussed, highlighting the advanced photocatalysts used. This Review is concluded by a brief summary and outlook for future advances in this emerging research field.

Decolorization of synthetic dyes by crude laccase from a newly isolated Trametes trogii strain cultivated on solid agro-industrial residue
Publisher: Elsevier BV
Date: 03-2011
DOI: 10.1016/J.JHAZMAT.2011.01.068
Abstract: A new dye-decolorizing white-rot fungus was isolated and identified as Trametes trogii based on its ITS-5.8S rRNA gene sequence analysis and morphological characteristics. Laccase was the only lignolytic enzyme produced by this strain during solid substrate fermentation (SSF) in soybean cake, a solid agro-industrial residue used for the first time in enzyme production. The extracellular crude enzyme from T. trogii in solid substrate fermentation showed good activity in synthetic dye color removal, decolorizing 85.2% Remazol Brilliant Blue R (50 mg l(-1)), 69.6% Reactive Blue 4 (35 mg l(-1)), and 45.6% Acid Blue 129 (83.3 mg l(-1)) without the addition of redox mediators, 90.2% Acid Red 1 (10 mg l(-1)), and 65.4% Reactive Black 5 (18.3 mg l(-1)) with the addition of 1mM 1-hydroxybenzotriazole in 30 min. Native polyacrylamide gel electrophoresis (Native-PAGE) of the crude enzyme and effects of laccase inhibitors on decolorization corroborated the laccase as the major enzyme involved in the decolorization of dyes. The comparison of color removal by the crude culture filtrates and by the whole fungal culture on the solid substrate revealed the former was more advantageous.
