Hot electrons derived from the surface plasmon resonance of metallic nanocrystals have been demonstrated to play a promising role in promoting the efficiency of photocatalytic and photoelectrochemical solar-to-fuel generation. In this review, we try to describe the underlying mechanisms of the generation and relaxation process of hot electrons, give a discussion on the key factors that affect the efficiency of hot electron injection from metal to semiconductor, and provide an overview of the research progress on hot electron-mediated photocatalytic and photoelectrochemical water splitting. This review also outlines the critical limitations in current studies and sheds light on the possible future developments in this research field.

Key words: metal/semiconductor heteronanocrystals, surface plasmon resonance, photocatalysis, photoelectrochemical catalysis, hot electron injection
