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.

Abstract H 2 O is recognized as one of the most significant chemicals, with extensive applications across various fields. This study presents in situ synthesis CdS/S‐doped g‐C 3 N 4 composite photocatalysts (CdS/CNS) via a simple one‐step thermal polymerization method by using thiourea and cadmium nitrate precursors. The synthesized materials were characterized XRD, adsorption, UV–vis, XPS, TEM, ESR, EIS, PL analysis. Experimental results have indicated that production rate on CdS/CNS photocatalyst was 4.2 times higher than single CNS under visible light illumination, well commendable catalytic stability. formed photocatalytic system effectively reduced recombination photo‐generated electron‐hole pairs, promoted response range light, enhanced specific surface area catalyst. A preliminary discussion potential reaction mechanisms also provided.

Designing and accumulating quantum dots (QD) onto layered double hydroxide (LDH) for the photocatalytic production of H2 H2O2 is a formidable task. Here, we intended synthesis procedure CdMoSe-QD (CMS)-incorporated NiV-LDH (NV) through facile in situ reflux method explored activities CMS/NV (CNV) heterostructure. CNV-1 exhibits large interface contact area assures excellent interfacial charge transfer ability. Moreover, outstanding rates, i.e., 6.4 2.5 times higher than that pristine NV, respectively, due to formation an S-scheme heterojunction between NV CMS. Both CMS function as n-type semiconductors extend photoresponse visible regions. The composite achieves 1.67% SCC generation 7.36% ACE evolution. activity ascribed anodic photocurrent, confinement effect CMS, surface-active sites, delayed recombination excitons supported by PL EIS measurements. Further, mechanism was authenticated radical scavenging test work function, evaluated UPS measurement. Altogether, this study exemplifies concepts designing CNV heterostructure, which operates via n–n-based aims enhance production.
