Effects of different manganese precursors as promoters on catalytic performance of CuO–MnOx/TiO2 catalysts for NO removal by CO

Abstract

Since the formation of the surface synergetic oxygen vacancy SSOV (Cu⁺–□–Mn³⁺) in the xCuyMn(N)/TiO₂ catalyst is easier than that (Cu⁺–□–Mn²⁺) in the xCuyMn(A)/TiO₂ catalyst, the activity of the xCuyMn(N)/TiO₂ catalyst is higher than that of the xCuyMn(A)/TiO₂ catalyst.
