摘要
利用沉积法获得了一维Fe_2O_3/α-MoO_3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,Fe_2O_3修饰一维α-MoO_3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%Fe_2O_3/α-MoO_3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-MoO_3纳米带和纯Fe_2O_3的光催化活性的3.8倍和26倍。
One Dimension（1D） heterostructure photocatalyst Fe2O3/ 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 Rh B was also explored. The test results show that the Fe2O3 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 Fe2O3weight 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 Fe2O3.
