摘要: 利用沉积法获得了一维Fe2 O3/α-MoO3异质结光催化剂,通过XRD、SEM-EDS、STEM、XPS、UV-Vis-DRS等测试手段对其组成、形貌、光吸收性质进行了表征,同时在可见光区测试了光催化氧化降解罗丹明B溶液的性能。测试结果表明,Fe2 O3修饰一维α-MoO3纳米带可将其光响应扩展至可见光区域,提高光催化性能。1wt;Fe2 O3/α-MoO3异质结作为光催化剂时,光照40 min后罗丹明B降解率可达到99;,分别是纯α-MoO3纳米带和纯Fe2 O3的光催化活性的3.8倍和26倍。

Abstract: One Dimension ( 1D ) heterostructure photocatalyst Fe2 O3/α-MoO3 was fabricated by depositional method, which its composition, morphology and photo-adsorption properties of were characterized by XRD、SEM-EDS、STEM、XPS、UV-Vis-DRS, as so as, the performance of photocatalytic degradation RhB was also explored. The test results show that the Fe2 O3 modification not only broaden the absorption spectrum of α-MoO3 nanobelt to the visible light region, but also increase the photocatalytic activity. The optimum photocatalytic activity of MoO3 at Fe2 O3 weight content of 1; could reach 99;after visible light irradiation 40 minutes, which is almost 3. 8 and 26 times as high as that of the pure MoO3 nanobelts and Fe2 O3 .
