Solar-driven photocatalytic water splitting faces inherent limitations in conventional liquid-solid systems, primarily due to sluggish reaction kinetics and catalyst deactivation. An emerging alternative employs photothermally generated water vapor reacting on a dry catalyst surface, which enhances performance by improving kinetics and preserving catalyst activity. This review systematically summarizes recent advances in this photothermal vapor-phase approach, with a focused analysis of the synergistic mechanisms between photothermal effects and photocatalysis at the vapor-solid interface. A key contribution of this work is the proposition of a novel system design paradigm centered on a slippery catalyst surface strategy, engineered to optimize vapor transport and interfacial interactions for enhanced efficiency. The rational design principles for integrated photothermal evaporation-catalysis systems are discussed in this context. This perspective aims to provide critical insights for the development of efficient, stable, and practical solar hydrogen generation technologies.
