制备了杂多化合物(C12H8N2)3.H3PMo12O40和空心结构复合催化剂(C12H8N2)3.H3PMo12O40/WO3,采用等离子体原子发射光谱(ICP-AES)、元素分析(EA)、热重-差热分析(TG-DTA)、X射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、扫描电镜(SEM)、能量色散X射线谱(EDS)、紫外-可见漫反射吸收光谱(UV-vis DRS)进行了表征。在高压汞灯照射下,研究了杂多化合物(C12H8N2)3.H3PMo12O40、空心WO3微球和空心复合催化剂(C12-H8N2)3.H3PMo12O40/WO3对罗丹明B水溶液的光催化降解活性,结果表明,在复合催化剂中,杂多化合物(C12-H8N2)3.H3PMo12O40和WO3具有协同作用,光催化活性比单独的杂多化合物和WO3都高。
(C12H8N2) 3.H3PMo12O40 and hollow-core composite catalyst (C12H8N2) 3.H3PMo12O40 / WO3 were prepared by plasma atomic emission spectrometry (ICP-AES), elemental analysis (EA), thermogravimetric-differential thermal analysis TG-DTA, XRD, FTIR, SEM, EDS, UV-vis DRS, Characterized. Under the irradiation of high pressure mercury lamp, the photocatalytic degradation activity of rhodamine B aqueous solution of heteropoly compound (C12H8N2) 3.H3PMo12O40, hollow WO3 microsphere and hollow composite catalyst (C12-H8N2) 3.H3PMo12O40 / WO3 was studied. In the composite catalyst, the heteropoly compound (C12-H8N2) 3.H3PMo12O40 has a synergistic effect with WO3, and the photocatalytic activity is higher than that of the heteropoly compound alone and WO3.
