Sr2InSbO6光催化分解水制氢的性能研究
本文采用高温固相法Sr2InSbO6光催化分解水制氢的性能研究合成了双钙钛矿型化合物Sr2InSbO6，对其粉末X射线衍射数据进行分析，证明了样品为纯相。由Sr2InSbO6的紫外漫反射光谱计算得到的带隙为3.5 eV。光催化活性测试表明，Sr2InSbO6在甲醇水溶液的制氢速率为48(4) μmol/g/h，负载Pt作为助催化剂后，其活性最高可达138(5) μmol/g/h。同时，Sr2InSbO6的衍射图在反应前后未发生明显变化，证明了其良好的稳定性。
he double perovskite compound Sr2InSbO6 was synthesized by high-temperature solid-state method. The catalyst was characterized by powder X-ray diffraction (PXRD). UV-Vis diffuse reflectance spectroscopy revealed an optical band gap of 3.5 eV. Photocatalytic evaluation demonstrated hydrogen evolution rate of 48(4) μmol/g/h in methanol aqueous solution, which increased to 138(5) μmol/g/h with Pt co-catalyst loading. The material exhibited excellent stability, as evidenced by unchanged XRD patterns before and after photocatalytic reactions.
