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.

2D/2D step-scheme (S-scheme) piezo-photocatalysts for the production of fine chemicals, such as hydrogen peroxide (H2O2), have attracted significant attention global scientists owing to efficiency in utilizing surface piezoelectric effects from 2D materials overcome rapid charge recombination photocatalytic processes. In this research, we reported fabrication S-doped VOx deposited on g-C3N4 produce H2O2 via piezo-photocatalytic process with high yields at 20.19 mmol g–1 h–1, which was 1.75 and 4.87 times higher than that solely piezo-catalytic generation. The finding pointed out adding sulfur (S) can help improve catalytic outcomes by modifying electronic properties pristine VOx. addition, when coupled g-C3N4, presence S limits formation graphene VOx/g-C3N4 composites, causing shielding pushing cascade reactions toward water generation materials. Besides, research also sheds light transport between S-VOx under irradiation how composites work trigger H2O2. composite systems enhances transfer two semiconductors strengthening internal electric fields (IEF) drive electrons moving one direction, demonstrated density functional theory (DFT) calculations. Moreover, significantly relies reduction oxygen generate oxygenic radical species sites. Meanwhile, provides oxidative sites oxidize molecules directly or indirectly O2, will further participate final products. This study confirms validation S-scheme piezo-photocatalysts, thus encouraging developing heterojunction efficiency, be used practical conditions.

Overall water splitting into H2 and H2O2 via Z-scheme piezo-photocatalytic systems is an ideal method for renewable energy production. Herein, we have synthesized a triangular prism-shaped metal–organic cage (MOC-Q3) integrating three catalytic Pd2+ centers two photosensitive ligands, which successfully immobilized on highly crystalline β-ketoenamine-linked covalent organic framework (EA-COF) to form single-atom photosystem. The optimized MOC-Q3/EA-COF achieves high yield (26.17 mmol g–1 h–1) with TONPd of 118,521 ascorbic acid as sacrificial agent due broad light absorption, effective carrier separation, widely distributed Pd active sites, among the highest COF-based solar evolution photocatalysts.
