摘要：

MoO3 ZeOlite (MoO3-NaY zeolite) catalyst was Prepared by the thermal decomposition of ammonium molybdate adsorbed in the NaY zeolite in aqueous media. The catalyst prepared thus was characterized by scanning electron microscope (SEM), measuring surface area (BET), X-ray diffraction, chemical analysis, effect of CO on adsorbed SO2, and the e.s.r. technique. The electron-accepting and -donating properties were also studied by measuring the concentration of thiophenazine cation radical (TPQD+) and tetracyanoethylene anion radical (TCNE-) formed. Ten percent MO+6 Of M003-NaY zeolite when activated at 450-degrees-C in vacuum changed to Mo'' ions. The formation of MO+3 WaS observed during S02 reduction by CO at 450-degrees-C.
