在这项工作中，首先通过共沉淀法合成了一系列MnxCd1-xS固溶体作为具有可见光响应的高效析氢光催化剂。然后，通过水热工艺将Mn0.2Cd0.8S复合材料与Bi2MoO6纳米晶复合，制备了分级Bi2MoO6/Mn0.2Cd0.8S异质结构复合材料。优化后的Mn0.2Cd0.8S复合材料的光催化活性是原始CdS的3倍以上，并且与单一Mn0.2Cd0.8S复合材料相比，制备的Bi2MoO6/Mn0.2Cd0.8S纳米复合材料在可见光响应的水中析氢光催化活性显着提高。 Bi2MoO6/Mn0.2Cd0.8S复合材料的优化光催化活性约为原始CdS的10倍。 Bi2MoO6/Mn0.2Cd0.8S复合材料优异的光催化活性可能归因于Bi2MoO6和Mn0.2Cd0.8S良好匹配的能带结构。此外，Bi2MoO6/Mn0.2Cd0.8S复合材料中的异质结也可能在一定程度上提高其光催化活性。提出了一种可能的光催化机制。由于其优异的光催化活性和良好的水中析氢稳定性，所获得的分级Bi2MoO6/Mn0.2Cd0.8S复合材料在太阳能光催化水中析氢方面具有潜在的应用前景。
In this work, a series of MnxCd1-xS solid solutions as efficient photocatalysts for hydrogen evolution with visible light response were synthesized via a co-precipitation method firstly. Then, the hierarchical Bi2MoO6/Mn0.2Cd0.8S heterostructured composite was prepared by combining Mn0.2Cd0.8S composite with Bi2MoO6nanocrystalline through a hydrothermal process. The optimized Mn0.2Cd0.8S composite's photocatalytic activity is more than 3 times of pristine CdS and the prepared Bi2MoO6/Mn0.2Cd0.8S nanocomposites exhibited a significantly improved photocatalytic activity for hydrogen evolution from water with visible light response comparing with single Mn0.2Cd0.8S composite. The optimized photocatalytic activity of Bi2MoO6/Mn0.2Cd0.8S composite is around 10 times of pristine CdS. The excellent photocatalytic activity of Bi2MoO6/Mn0.2Cd0.8S composite might be ascribed to the well-matched energy band structures of the Bi2MoO6and Mn0.2Cd0.8S. Furthermore, the heterojunctions in Bi2MoO6/Mn0.2Cd0.8S composite might also do some contributions to improve its photocatalytic activities to some extent. A possible photocatalytic mechanism was proposed. Due to its excellent photocatalytic activity and good stability for hydrogen evolution from water, the obtained hierarchical Bi2MoO6/Mn0.2Cd0.8S composite has potential application in photocatalytic hydrogen evolution from water by using solar power.
