摘　　要：在国内外最新文献的基础上总结了制备分级结构WO3粉体材料的主要方法:即水热法、模版法、溶胶-凝胶法、热解法,并且讨论了各种方法的优缺点及研究进展;论文中还介绍了WO3粉体材料的形貌对光催化性能的影响;通过查阅相关的文献发现催化剂的形貌不同,比表面积就不同,比表面积越大,催化性能越好,而分级结构WO3粉体材料因其特殊的形貌,具有更大的比表面积,因此光催化性能较未组装前好。based on many domestic and overseas documents, in this paper synthetic methods of hierarchical WO3 powder were introduced, such as hydrothermal method, template method, sol-gel method and pyrolysis method. At the same, their advantages and disadvantages and the research progress of WO3 were reviewed. The morphology of WO3 had an influence up on its photocatalytic properties, which was introduced in the paper. The different of morphology, the specific surface area was different, and the bigger of specific surface area, the bette of photocatatytic performance, so the hierarchical structure of WO3 powder material because of its special morphology, with larger specific surface area, photocatalytic performance was better before assembly.
