Impact of bimetallic synergies on Mo-doping NiFeOOH

The oxygen evolution reaction (OER) is a vital yet challenging process in water splitting, requiring a four-electron transfer that often suffers from slow reaction kinetics. Noble metal-based oxides, such as RuO2 and IrO2, have been the go-to catalysts for this process, but their scarcity and high cost have motivated the search for alternative, non-precious metal catalysts.
