Abstract
Abstract In the energy transition context, the design and synthesis of high‐performance Pt‐based photocatalysts with low Pt content and ultrahigh atom‐utilization efficiency for hydrogen production are essential. Herein, a facile approach for decorating atomically dispersed Pt cocatalysts having single‐atom (SA) and atomic cluster (C) dual active sites on CdS nanorods (Pt SA+C /CdS) via atomic layer deposition is reported. The size of the cocatalyst and the spatial intimacy of the cocatalyst active sites are precisely engineered at the atomic scale. The Pt SA+C /CdS photocatalysts show the optimized photocatalytic hydrogen evolution activity, achieving a reaction rate of 80.4 mmol h −1 g −1 , which is 1.6‐ and…
