摘要

WO3是最有潜力的光催化剂之一。但由于其还原能力较差，要实现光催化制氢，还需要与WS2结合等改性。为了找出WO3与WS2的最佳配比，本文采用简单的两步煅烧法制备了一系列WO3-WS2复合材料，并在红素B钠盐（EB）敏化下研究了其光催化氢性能。结果表明，当WS2与WO3的质量比大于等于5:5时，可以实现高效析氢。此外，还对制备前驱体WO3的煅烧条件和WO3- ws2复合材料的制备方法进行了优化。制备的WO3-WS2具有较好的稳定性，并且在引入CdS后，可以实现相对稳定的产氢。

Synthesis and photosensitized hydrogen production of WO3-WS2 composite

WO₃ is one of the most potential photocatalysts. However, to realize its photocatalytic hydrogen production, modification such as combining with WS₂ is necessary due to its poor reduction capacity. To find out the optimal ratio between WO₃ and WS₂, in this paper, a facile two-step calcination method was used for the preparation of a series of WO₃-WS₂ composites, and their photocatalytic hydrogen performances were investigated under Erythrosine B sodium salt (EB) sensitization. The results showed that when the mass ratio of WS₂ to WO₃ is 5:5 or higher, efficient hydrogen evolution comes true. In addition, the calcination condition for the preparation of precursor WO₃ and the method for the preparation of WO₃-WS₂ composite were optimized. The as-prepared WO₃-WS₂ exhibits relatively good stability and relatively stable hydrogen generation was achieved when CdS was introduced.
