The origin of stoichiometric effects in nickel-tungsten alloy catalysts

A research group led by Professor Gao Minrui from the University of Science and Technology of China (USTC) reports that nickel-tungsten (Ni-W) ratio in Ni-W alloys governs the performance of hydrogen oxidation reaction (HOR). Additionally, researchers tuned the unpaired electrons in Ni to adjust the potential of zero charge (PZC) and hydroxyl adsorption (OHad) capacity of the alloy in alkaline HODs. The results have been published in Angewandte Chemie International Edition.
