Plasma-Derived Atomic Hydrogen Enables Eley-Rideal-Type CO Methanation at Low Temperatures.

Activating H molecules into atomic hydrogen and utilizing their intrinsic chemical reactivity are important processes in catalytic hydrogenation. Here, we have developed a plasma-catalyst combined system that directly provides atomic hydrogen from the gas phase to the catalytic reaction to utilize the high energy and translational freedom of atomic hydrogen. In this system, we show that the temperature of CO methanation over Ni/AlO can be dramatically lower compared to thermal catalysis.

Mechanochemistry and mechanocatalysis are gaining increasing attention as environmentally friendly chemical processes because of their solvent-free nature and scalability. Significant effort has been devoted for studying continuum-scale phenomena in mechanochemistry, such as temperature and pressure gradients, but the atomic-scale mechanisms remain relatively unexplored. In this work, we focus on the mechanochemical reduction of MoO as a case study.

Individual molecules dissolved in a dilute solution are usually considered not to correlate with each other as they undergo chemical reactions due to the mismatch of the diffusion and reaction time scales. Recent studies suggest otherwise, especially for reactions involving macromolecules. With selenopolypeptides as a model system, we used ensemble measurements and single-molecule direct imaging to investigate the correlation between physically constrained chemical reaction sites on a linear polymer chain and the coupling effects between conformation changes and reaction kinetics.

Freshwater pearl farming in China generates wastewater high in ammoniacal nitrogen (NH₃-N) posing environmental threats. This study explores the use of coal fly ash (CFA), an industrial waste, to synthesize A-type zeolite for effective NH₃-N removal from pearl farming wastewater. The zeolite was prepared via pickling pretreatment and hydrothermal methods, resulting in a material with favorable adsorption properties, including cubic and spherical microstructures, a specific surface area of 17.

Department of Chemistry, University of York York YO10 5DD UK
C-N atropisomeric amides are important compounds in medicinal chemistry and agrochemistry. Atropselective methods for their synthesis are therefore important. In this study, a novel strategy to make C-N atropisomeric amides based on intramolecular acyl transfer a tethered Lewis basic pyridine or tertiary amine group is reported.
