Abstract

. Electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) analyses confirm the enhanced capability of this heterostructure in hydrogen adsorption and desorption. Ultraviolet photoelectron spectroscopy (UPS) and X-ray photoelectron spectroscopy (XPS) tests reveal electron rearrangement at the interface, verifying the existence of hydrogen spillover pathways. Additionally, the superhydrophilic-superaerophobic wetting characteristics of the catalyst surface help improve the diffusion rate of reactants and the desorption efficiency of products, thereby further enhancing the overall catalytic stability.
