Solid State Synthesis of Transition Metal Molybdovanadophosphate Nanoparticles
Abstract:
Four polyoxometalate particles H3MPMo10V2O40·xH2O(M=Co2+,Ni2+,Cu2+,Zn2+) were synthesized by solid-state reaction at room temperature. Their structures, particle sizes, thermal properties and surface properties were investigated by IR, UV, XRD, TEM, TG-DTA and TPR techniques. The results show that these four polyoxometate particles have Keggin structure with size being 32~42 nm. The thermal stability of the polyoxometalates appeared decreased, but surface activity increased significantly, when they are in nanoparticles form.
