摘要 以CTAB为模板剂,钨酸钠为反应物前体,在碱性条件下,用室温法和水热法合成了介孔三氧化钨。X射线衍射分析表明,室温条件下生成的是层状相的介孔材料,而在水热条件下可生成六方相的介孔结构,最适宜的水热时间为2天,水热温度为110℃。400℃煅烧处理后,介孔结构基本坍塌。 Mesoporous tungsten trioxide materials was synthesized in alkaline condition. XRD demonstrated the lamellar phase can be synthesized via room temperature method and the hexagonal phase can be synthesized by hydrothermal reaction. The optimum time for hydrothermal systhesis is 2 days. The optimum hydrothermal temperature is 110℃. Mesoporous strusture has been destructed when calcining temperature is 400℃.
