【摘要】 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。更多还原

【Abstract】 Heteropoly compound(C12H8N2)3·H3PMo12O40 and hollow structured hybrid catalyst(C12H8N2)3·H3-PMo12O40/WO3 were prepared and characterized via inductively coupled plasma atomic emission spectroscopy(ICP-AES),elemental analysis(EA),thermogravimetry-differential thermal analysis(TG-DTA),powder X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR),scanning electron microscopy(SEM),energy-dispersive X-ray spectrometry(EDS) and UV-vis diffuse reflectance spectroscopy(UV-vis DRS).Photocatalytic performance of the synthesized heteropoly compound(C12H8N2)3·H3PMo12O40,WO3 hollow microspheres and hollow structured hybrid catalyst(C12H8N2)3·H3PMo12O40/WO3 were tested by photocatalytic decomposition of rhodamine B aqueous solution under irradiation of high pressure mercury lamp.The results show that the activity of hollow hybrid catalyst is higher than that of heteropoly compound(C12H8N2)3·H3PMo12O40 and WO3 hollow microspheres respectively,which is ascribed to the synergistic effect between heteropoly compound and tungsten trioxide in the hybrid catalyst(C12H8N2)3·H3PMo12O40/WO3.更多还原
