Propane oxidative dehydrogenation (OXD) over V-Mg-O and MCl_n(M=Cu~+, Li~+, Ag~+, Cd~(2+))-promoted V-Mg-O catalysts was studied. XRDresult showed that the V-Mg-O catalysts were composed of MgO andMg_3(VO_4)_2. The promtion effects of CuCl and LiCl were significant, but ofAgCl and CdCl_2 were not efficient. XPS results indicated that on the catalystthere existed two kinds of oxygen species, lattice oxygen O~(2-) and adsorptiveoxygen (O_2~-). They affected the catalytic activity and selectivity in the OXDof propene.
