摘　　要：Three PMoV heteropoly acids(HPAs)with different number of V atoms were synthesized and characterized by ICPAES,TG,IR and XRD.The IR spectra indicated that they are Keggin structure.Compared the IR spectrum of PMo HPA with those of PMoV HPAs,it was found that the characteristic absorption peak values(CAPV)of all of the PMoV HPAS were redshifted.Three PMoV heteropoly acids(HPAs)with different number of V atoms were synthesized and characterized by ICPAES,TG,IR and XRD.The IR spectra indicated that they are Keggin structure.Compared the IR spectrum of PMo HPA with those of PMoV HPAs,it was found that the characteristic absorption peak values(CAPV)of all of the PMoV HPAS were redshifted.
