Gang Wu Research Group

The group engineered a heterostructure catalyst combining rhenium phosphide and molybdenum phosphide to boost catalytic activity for alkaline water electrolysis. Researchers integrated the new PGM-free cathode with a nickel-iron anode and tested it at industry-level current densities (1–2 A cm–2) to evaluate performance and durability. Experiments examined hydrogen adsorption/desorption roles of rhenium and proton-supplying kinetics accelerated by molybdenum, linking composition to reaction mechanisms. The team analyzed catalyst/electrolyte interface hydrogen-bond network engineering to lower resistance and improve hydrogen adsorption kinetics in membrane electrode assemblies.
