Catalytic combustion of chlorobenzene over Mn–Ce/Al2O3 catalyst promoted by Mg

Mn–Ce–Mg/Al2O3 catalyst prepared by a wet impregnation method was investigated in the catalytic combustion of chlorobenzene. The addition of Mg decreased the interaction of Mn and Ce species with Al2O3 and promotes the dispersion of Mn and Ce species and the formation of Ce–Mn–O solid solution. High activity, good selectivity and desired stability of Mn–Ce–Mg/Al2O3 catalyst were observed.
