Highly effective and efficient remediation of hazardous Ni waste from electroless electroplating wastewater remains a significant challenge. However, rather than regarding it as hazardous waste, Ni-electroplating wastewater can instead be considered a huge resource of Ni. Herein, we report a convenient hydrothermal strategy for upcycling Ni from nickel-electroplating wastewater into a carbon-doped Ni-P alloy (denoted as C/Ni-P) electrocatalyst for the oxidation of glycerol to formate.

Photocatalytic upcycling of waste polyolefins into value-added chemicals provides promise in plastic waste management and resource utilization. Previous works demonstrate that polyolefins can be converted into carboxylic acids, with CO as the final oxidation product. It is still challenging to explore more transformation products, particularly mild-oxidation products such as alcohols, because of their instability compared with polymer substrates, which are prone to oxidation during catalytic reactions.

Nicotinamide adenine dinucleotide is a crucial coenzyme in cellular metabolism and is implicated in various diseases. This work introduces an electrochemical bioanalytical method utilizing solution-phase formate dehydrogenase (CbFDH) for detecting its oxidized form (NAD) in human blood plasma samples. The detection mechanism involves the catalytic conversion of NAD to NADH, facilitated by CbFDH in the presence of formate.

Since water is both a product and a common reactant impurity in the (partial) methanol oxidation to methyl formate (MeFo) on gold, its effect on the isothermal selectivity to methyl formate was investigated under well-defined single-collision conditions employing pulsed molecular beam experiments and in situ IRAS measurements. Both a flat Au(111) and a stepped Au(332) surface were used as model catalysts to elucidate how water affects the reactivity of low-coordinated step sites as compared to (111) terrace sites employing a range of reaction conditions. The interactions of water with methanol/methoxy as well as with oxygen species are addressed.

Solar hydrogen production using photoelectrochemical (PEC) cells requires the selection of cost-effective materials with high photoactivity and durability. CuBiO photocathodes possess an appropriate bandgap for efficient hydrogen production. However, their performance is limited by poor charge transport and interface voids formed due to the porous structure during annealing, which complicates the deposition of passivation overlayers.
