摘要：VO2(M) doped with different metals(Ti, Ce, Nb, Zr, W, and Mo) was successfully synthesized by the hydrothermal reduction process using oxalic acid as the reductant. The results showed that doping metals in the VO2(M) lattice could enhance the oxidative desulfurization(ODS) activity. The DSC and Raman spectra revealed that VO2(M) retained its monoclinic structure after doping. Mechanism for the improvement of ODS activity by doping was investigated. Electron transfer to V(V) atom occurs upon doping, and then V(V) changes into V(IV), which can promote the ODS reaction. This explanation can be confirmed by the fact that doping can promote the proportion of V(Ⅳ) after doping as revealed by the XPS analysis.
