Summary: Utilizing OH- oxidation as a counter reaction to CO2 electroreduction can increase formate production rate and faradic efficiency. Alkaline anolyte helps stabilize catholyte pH, avoiding competitive hydrogen evolution reaction, and has the lowest power consumption compared to other anolytes.

Summary: This study investigated the evolution of various bismuth-based catalysts during reaction and found that their morphology changed with the formation of Bi2O2CO3 layers, which facilitated the reduction of metallic bismuth. The final phase and morphology depended on the size of the bismuth precursor. Quasi-in situ XPS analysis revealed the persistence of Bi2O2CO3 contribution on the surface of the reduced catalysts.

Summary: A novel terpyridine-based Ru(ii) complex was synthesized and its spectroscopic, electrochemical, and catalytic properties were investigated. The complex exhibited two reduction peaks in dry acetonitrile, attributed to consecutive 1 e(-) reduction. Under CO2 atmosphere, a catalytic wave was observed, with CO as the main reduction product. The presence of water improved the catalytic activity and formate production was detected.

Summary: In this study, metal-doped LaMnO3 was explored as an anode catalyst for CH3OH oxidation to produce HCOOH, and Cu-M (M = Pd, Pb, Bi, Sn, and In) bimetal catalysts were used as cathode catalysts for CO2 reduction to HCOOH. The results showed that metal-doped LaMnO3 could facilitate CH3OH oxidation by reducing the overpotential, and B-site metal-doped effect was better than A-site metal-doped effect. Pb@Cu catalyst exhibited excellent catalytic activity for CO2 reduction to HCOOH.

Summary: The study compared the performance of 3D nanoparticles and 2D nanosheets as catalysts for electrochemical CO2 conversion to formate, finding that a catalyst with extensive interface could enhance CO2 reduction selectivity but require higher overpotential. Therefore, the catalyst-substrate interface structure plays a crucial role in determining the performance of gas-diffusion electrodes in such processes.

Summary: The use of silver nanoparticles (AgNPs) for photothermal disinfection of PPE has shown promising results in deactivating the SARS-CoV-2 virus responsible for the COVID-19 pandemic. The AgNP/protectant composites demonstrated monodisperse spherical particles of 5-10 nm in diameter, activated by blue light-emitting diodes to elevate surface temperatures up to 150 degrees C. The photothermal activation was found to be highly efficient and durable over long periods of exposure, with potential improvement in washing resistance through chitosan cross-linking.
