A research team led by Prof. Gao Minrui from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has developed a nickel (Ni)-based anion-exchange membrane fuel cell (AEMFC) anode catalyst with high resistance to ammonia (NH3) toxicity. The work was published in Journal of the American Chemical Society.
to obtain electron-rich states.
By doping chromium into the efficient hydrogen oxidation catalyst molybdenum-nickel alloy , the team not only obtained the electron-rich states of Ni to suppress the electron supply of σ*Rotating-disk electrode tests showed that the Cr-doped catalyst Cr-MoNiwithout significant activity decay, while traditional Pt/C catalyst suffered severe decay under such conditions. In actual alkaline membrane fuel cells assembled with Cr-MoNi, in contrast to 65% of Pt/C catalyst.

Researchers develop new selective emitter based on iridium for thermophotovoltaicsResearchers from the Helmholtz-Zentrum Hereon, together with the Technical University of Hamburg and Aalborg University, have developed a new selective emitter based on iridium for thermophotovoltaics. Iridium was thus used for the first time as a material for an emitter, and in the experiments, it showed particular endurance at high temperatures around 1,000°C. Their study results were published in the journal Advanced Materials and open up new perspectives for producing electricity from heat.

Researchers create optical device that can kill pathogens on surfaces while remaining safe for humansWhile it has long been known that ultraviolet (UV) light can help kill disease-causing pathogens, the COVID-19 pandemic has put a spotlight on how these technologies can rid environments of germs. However, the excimer lamps and LEDs that can directly emit light in the required deep-UV wavelengths generally have low efficiency or suffer from short lifetimes. Moreover, UV light of the wrong wavelength can actually be harmful to human cells.

Researchers improve efficiency in carbon dioxide electroreductionResearchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences and Yanshan University have proposed a strategy for boosting the CO faradaic efficiency in electrocatalytic CO2 reduction reaction (eCO2RR), an attractive option to address serious climate concerns and produce value-added chemical feedstock via coupling with renewable energies. The strategy is promising in producing CO via eCO2RR at ambient conditions.
