Interface Charge Transfer Engineering in NiFe Layered Double Hydroxide-Cs_0.32WO₃ Heterostructures for Enhanced Oxygen Evolution Reaction.

ABSTRACT: Electrochemical water splitting for hydrogen production is considered a key pathway for achieving sustainable energy conversion. However, the sluggish reaction kinetics of the oxygen evolution reaction (OER) and high overpotentials severely hinder the large-scale application of water electrolysis technology. Nickel-iron layered double hydroxide (NiFe-LDH) has gained attention as a promising non-precious metal OER catalyst due to its abundant active sites and good intrinsic activity. However, its relatively low conductivity and charge transfer efficiency limit the improvement of catalytic performance. Therefore, this study used a simple hydrothermal method to generate a NiFe-LDH/Cs0.32WO3 heterojunction composite catalyst, relying on the excellent electronic conductivity of Cs0.32WO3 to imp
