摘要:
为实现钙钛矿基半导体复合材料的高效光解水产氢，以钙钛矿相钛酸铅（PbTiO 3，PTO）微米片为衬底，采用水热法制备钙钛矿相钛酸铅硫化镉（PTO CdS）微米片复合材料。探究水热温度和CdS负载量对复合材料的形貌及物相的影响；通过TEM、XPS及UV Vis对复合材料的微结构、表面化学状态和光吸收特性进行表征；通过光解水产氢实验对复合材料的光催化活性进行测定和分析。结果表明：水热条件下，钙钛矿相PTO微米片对CdS的生长具有显著调控作用，与单独生长时尺寸约3 μm的枝杈晶形貌不同，PTO CdS微米片复合材料中的CdS为三角形纳米颗粒，尺寸约50 nm，均匀分散地生长在PTO微米片表面，且PTO与CdS之间界面清晰；水热温度和CdS负载量对复合材料的形貌和物相影响显著，水热温度为160 ℃、CdS负载量为6%时制备的PTO CdS微米片复合材料尺寸均一，负载均匀，纯度和结晶度良好；PTO CdS微米片复合材料在模拟太阳光下表现出光催化分解水产氢特性，其中PTO CdS 6%的产氢速率达到141.45 μmol/h/g，是PTO微米片产氢效率的17倍，是CdS枝杈晶产氢效率的53倍。该研究为高效钙钛矿基半导体复合光催化剂的设计提供了思路。
