摘要：

H3PMo12O40 with Keggin structure was supported on three-dimensionally ordered macroporous (3DOM) SiO2 to synthesize a new-type 3DOM composite material of H3PMo12O40-SiO2. Through comparative analysis of H(3)PMo(12)O(4)0 and 3DOM H3PMo12O40-SiO2, it could be found that the thermal stability of H3PMo12O40 was increased after supporting and that Keggin structure was remained also in 3DOM H3PMo12O40-SiO2, but the crystalline form was changed. Moreover, H3PMo12O40 Combined with SiO2 tightly and the synthesized H3PMo12O40-SiO2 had unique porous structure like crown and interconnected through small windows.
