A Sm2Ti2S2O5 (STSO) oxysulfide photocatalyst prepared by a novel flux method showed a higher degree of crystallinity and greater photocatalytic activity than that prepared by conventional polymerized complex and sulfurization processes. Co-loading with both IrO2, as an oxidative cocatalyst, and Pt, as a reductive cocatalyst, was found to be essential for promoting the photocatalytic activity of the STSO. Visible light-driven Z-scheme water splitting into H2 and O2 was realized by utilizing the STSO photocatalyst for H2 evolution in conjunction with a WO3 photocatalyst treated with H+ and Cs+ and loaded with PtOx for O2 evolution, and a triiodide/iodide (I3–/I–) redox couple as a shuttle electron mediator. Various other narrow band gap oxysulfide photocatalysts with H2 evolution activity, such as La5Ti2CuS5O7 and La6Ti2S8O5, were also shown to be applicable as H2 evolution photocatalysts in the present Z-scheme water splitting system.

使用氧硫化物H 2逸出光催化剂的可见光驱动Z方案水分解
通过新型助熔剂方法制备的Sm 2 Ti 2 S 2 O 5（STSO）氧硫化物光催化剂比常规聚合的络合物和硫化方法制备的Sm 2 Ti 2 S 2 O 5（STSO）氧硫化物具有更高的结晶度和更高的光催化活性。发现与作为氧化助催化剂的IrO 2和作为还原助催化剂的Pt的共同负载对于促进STSO的光催化活性至关重要。通过将STSO光催化剂用于H 2的释放以及结合H +处理的WO 3光催化剂，实现了可见光驱动的Z方案水分解为H 2和O 2的分解。和Cs +并负载PtO x以释放O 2，并用三碘化物/碘化物（I 3 – / I –）氧化还原对作为穿梭电子介体。还显示了具有H 2析出活性的各种其他窄带隙氧化硫光催化剂，如La 5 Ti 2 CuS 5 O 7和La 6 Ti 2 S 8 O 5，也可用作本Z方案中的H 2析出光催化剂。分水系统。
