Abstract
The dissociative chemisorption and energetically driven migration of atomic hydrogen on heterogenous electrocatalysts, i.e., hydrogen spillovers, which occur during electrochemical turnovers, have been intensively investigated recently on high-performance electrocatalysts for hydrogen evolution reaction. The elucidation of the hydrogen spillover not only reshapes the mechanistic understanding of the catalytic landscape but also aids in formulating efficient reaction pathways for catalyst designs. This perspective hence concisely summarizes the status of research on the hydrogen spillover effect in recent years, as well as the experimental methods to characterize the hydrogen spillover process and presents a prospect for future research direction.
