ZnWO4-ZnIn2S4 S-scheme heterojunction for enhanced photocatalytic H2 evolution
文献摘要：
The recombination of photogenerated electrons and holes is a crucial factor limiting photocatalytic H2 evolution.The S-scheme ZnWO4-Znln2S4 heterojunction with 2D coupling interfaces was successfully syn-thesized using a simple solvothermal method.An effective S-scheme interfacial charge migration route at the S-scheme heterogeneous interface was determined by energy band structure analyses(such as UPS,Mott-Schottky and XPS plots),which facilitates the separation of photoexcited carriers.It is worth noting that the optimal ZnWO4-Znln2S4 composite has an H2 evolution activity of 4925.3 μmol g-1 h-1 with favourable photostability and stability.Meanwhile,the ZnWO4-Znln2S4 heterojunction exhibits the maxi-mum optical response value(2.8 mA cm-2)in the initial stage,effectively promoting the separation and migration of photogenerated carriers.The establishment of the built-in electric field direction at the in-terface can effectively promote the space charge separation between the ZnWO4 and ZnIn2S4 nanosheets,which is favorable to the photocatalytic H2 evolution.This work provides valuable guidance for designing S-scheme heterojunction photocatalysts composed of two n-type semiconductors for energy and environ-mental applications.
