Summary: The oxidation of diaryl sulfides and aryl alkyl sulfides to sulfoxides and sulfones under electrochemical conditions was studied. Sulfoxides were selectively obtained in DMF with a constant current of 5 mA for 10 hours, while sulfones were the major products in MeOH with a constant current of 10 or 20 mA for 10 hours. The oxygen in both sulfoxides and sulfones is derived from water.

Summary: Single-atom catalysts (SACs) combining the advantages of both heterogeneous and homogeneous catalysts have become the forefront in advanced oxidation processes (AOPs). Carbon-based single-atom Fe catalysts (Fe-SACs) with nitrogen doping have attracted attention in environmental catalysis due to their high activity, selectivity, and stability. However, there is a lack of comprehensive reviews on the use of carbon-based Fe-SACs for AOPs degradation of organic water pollution.

Summary: In this study, an ethylene glycol-based electrolyte was used to electrodeposit copper onto zinc for the synthesis of the precursor of Cu2ZnSnS4. The optimal concentration of DEA for copper complexation, the effect of amine on the reduction potential of copper species, and the displacement reaction between copper and zinc were investigated. The optimized copper solution allowed for the electrochemical synthesis of Mo-(sub)/Zn/Cu/Sn stack on a relatively large area, leading to the formation of Kesterite CZTS phase. Photoelectrochemical water splitting on CZTS/CdS/Pt heterostructure exhibited a promising photocurrent and photon-to-current efficiency.

Summary: A series of TEMPO@PCN-222 composite photocatalysts were developed by coordinating different amount of 4-carboxy-TEMPO with the secondary building units of PCN-222. Visible-light irradiation enables the transfer of photogenerated holes in the highest occupied molecular orbital of PCN-222 to TEMPO, significantly increasing the photosynthesis of bioactive (iso)quinolones. With an outstanding catalytic stability and substrate tolerance, TEMPO@PCN-222 exhibits a yield of 86.7% for 1-methyl-2-quinolinone, over four times higher than PCN-222 (21.4%). This study provides a new route for constructing composite photocatalysts from abundant starting materials for efficient photosynthesis of high value-added chemicals.

Summary: Zinc molybdate with a disordered layered stacking structure was prepared using an evaporation method and demonstrated excellent catalytic performance for selectively converting lignocellulose-derived ketones to olefins. The outstanding catalytic performance was attributed to its porous structure, higher oxygen vacancy concentration, and higher acidity. Additionally, it also exhibited good catalytic performances for other lignocellulose-derived ketones.

Summary: Biomass reforming using solar energy allows for the production of green hydrogen. Current biomass photoreforming inefficiently produces hydrogen due to intermittent solar light and incomplete degradation of biomass C-C bonds. This study overcomes these issues by converting carbohydrates into liquid hydrogen carriers (LHCs) suitable for transportation. The LHCs are then fully decomposed, releasing only H2 and CO2. By prioritizing complete scission of carbohydrate C-C bonds, this process yields 44 g of H2 per kg of glucose. This work demonstrates the production and storage of hydrogen through the complete breakdown of biomass C-C bonds.

Summary: In this work, selective ethylene carbonylation to 3-pentanone was achieved using in situ produced hydrogen via a water-gas shift (WGS) reaction on a defective ceria-supported Rh catalyst. The interface of Rh/CeO2 activates water, CO, and ethylene, facilitating the WGS reaction and ethylene carbonylation. A redox pathway for the WGS reaction was proposed based on in situ FTIR results, and water was confirmed as the hydrogen source for ethylene carbonylation through mass spectrometry (MS) study.

Summary: In this study, a CuOx-loaded Nb2O5 photocatalyst was designed, which selectively catalyzes the oxidation of furfural to produce maleic anhydride and its precursor. By loading CuOx and forming a complex, the catalyst can efficiently absorb visible light to activate furfural, leading to C-C bond cleavage and CO generation. This method provides a mild approach for the production of renewable maleic anhydride.

Summary: This study reports a novel photocatalytic strategy for the oxidative C-C cleavage of lignin and β-O-4 derivatives using photoredox organocatalysts. High yields of aromatic aldehydes and phenyl formate were obtained, and mixed binary organic solvents were shown to promote bond cleavage and inhibit over-oxidation side reactions. The absorbance, excitation, and interaction with the lignin model of the photocatalyst in different solvents were investigated, and a C-centered radical intermediate was captured, providing evidence for the direct Cα-Cβ bond cleavage mechanism.

Summary: The interfaces in heterogeneous catalysts have a crucial role in their performances by providing active sites through synergistic effects or modulating the state of active sites. Constructing abundant interfaces in heterogeneous catalysts is challenging due to the high dispersion required for all catalyst compositions involved in substrate activation. A surface reduction strategy is proposed as a solution to this challenge, where a pyramid-type catalyst, (Pt/4nmCeO(2))/SiO2, with maximized interfacial Pt-CeO2 sites is created. This work aids in the development of heterogeneous catalysts by enabling a high level of control over the local chemical environment within nanomaterials.
