Abstract Developing conductor‐mediated S‐scheme heterojunction photocatalysts imitating natural photosynthetic systems emerges as a promising approach to hydrogen peroxide (H 2 O ) production. However, achieving precise coupling between two semiconductors with charge shuttle and modulating the interfacial interactions still remain significant bottleneck. Herein, we propose catalyst architecture Cd single atom mediated formed by interfacing CdS TiO nanoparticles. This exhibits an H production rate high 60.33 µmol g −1 min under UV–vis light irradiation, which is attributed efficient transport at interface of thanks S‐scheme. In‐situ X‐ray photoelectron spectroscopy (XPS) electron spin resonance (ESR) spin‐trapping tests confirm transfer route. Femtosecond transient absorption (fs‐TA) other ex‐situ characterizations further corroborate across interface. work offers new perspective on constructing atoms heterojunctions enhance photocatalytic performance.
