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。Heteropoly compound （C12H8N2）3·H3PMo12O40/WO3 and hollow structured hybrid catalyst（C12H8N2）3·H3PMo12O40/WO3were prepared and characterized via inductively coupled plasma atomic emission spectroscopy （ICP-AES）, elemental analysis （EA） , thermogravimetry-differential thermal analysis（TG-DTA）, powder X-ray dif- fraction （XRD）, Fourier transform infrared spectroscopy （FTIR）, scanning electron microscopy（SEM）, energy-dis- persive X-ray spectrometry （EDS） and UV-vis diffuse reflectance spectroscopy（UV-vis DRS）. Photocatalytic per- formance 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/WO3 hollow microspheres re spectively, which is ascribed to the synergistic effect between heteropoly compound and tungsten trioxide in the hybrid catalyst（C12H8N2）3·H3PMo12O40/WO3.
