Abstract：

This　study　details　the　rational　design　and　synthesis　of　Cu2ZnSnS4　(CZTS)-doped　anatase　(A)　heterostructures,　utilizing　earth-abundant　elements　to　enhance　the　efficiency　of　solar-driven　water　splitting.　A　one-step　hydrothermal　method　was　employed　to　fabricate　a　series　of　CZTS–A　heterojunctions.　As　the　concentration　of　titanium　dioxide　(TiO2)　varied,　the　morphology　of　CZTS　shifted　from　floral　patterns　to　sheet-like　structures.　The　resulting　CZTS–A　heterostructures　underwent　comprehensive　characterization　through　photoelectrochemical　response　assessments,　optical　measurements,　and　electrochemical　impedance　spectroscopy　analyses.　Detailed　photoelectrochemical　(PEC)　investigations　demonstrated　notable　enhancements　in　photocurrent　density　and　incident　photon-to-electron　conversion　efficiency　(IPCE).　Compared　to　pure　anatase　electrodes,　the　optimized　CZTS–A　heterostructures　exhibited　a　seven-fold　increase　in　photocurrent　density　and　reached　a　hydrogen　production　efficiency　of　1.1%.　Additionally,　the　maximum　H2　production　rate　from　these　heterostructures　was　11-times　greater　than　that　of　pure　anatase　and　250-times　higher　than　the　original　CZTS　after　2　h　of　irradiation.　These　results　underscore　the　enhanced　PEC　performance　of　CZTS–A　heterostructures,　highlighting　their　potential　as　highly　efficient　materials　for　solar　water　splitting.　Integrating　Cu2ZnSnS4　nanoparticles　(NPs)　within　TiO2　(anatase)　heterostructures　implied　new　avenues　for　developing　earth-abundant　and　cost-effective　photocatalytic　systems　for　renewable　energy　applications.　©　2024　by　the　authors.
