摘要
Abstract
Fe(Ⅱ)-MnO2,Co(Ⅱ)-MnO2,Ni(Ⅱ)-MnO2,and Cu(Ⅱ)-MnO2 catalysts were prepared by in-situ doping of transition metals Fe2+,Co2+,Ni2+,and Cu2+with MnO2.The types of modified transition metals were selected,and the molar ratio of transition metals to MnO2 was optimized.The water vapor resistance and service life of the selected catalyst were tested.The experimental results show that compared with undoped MnO2,the catalytic oxidation activity of Fe(Ⅱ)-MnO2 for toluene is improved,while the catalytic oxidation performance of catalysts doped with the other three transition metals for toluene is reduced.The optimal ratio of FeSO4 to MnSO4 in Fe(Ⅱ)-MnO2 catalyst is 1.0∶5.The Fe(Ⅱ)-MnO2 catalyst exhibits good resistance to water vapor and strong activity stability and persistence.关键词
