Bauxite-supported Transition Metal Oxides: Promising Low-temperature and SO(2)-tolerant Catalysts for Selective Catalytic Reduction of NO(x)

In order to develop low-temperature (below 200 °C) and SO(2)-tolerant catalysts for selective catalytic reduction (SCR) of NO(x), a series of cheap M/bauxite (M = Mn, Ni and Cu) catalysts were prepared using bauxite as a support. Their SCR performances are much superior to typical V(2)O(5)/TiO(2), t...

description In order to develop low-temperature (below 200 °C) and SO(2)-tolerant catalysts for selective catalytic reduction (SCR) of NO(x), a series of cheap M/bauxite (M = Mn, Ni and Cu) catalysts were prepared using bauxite as a support. Their SCR performances are much superior to typical V(2)O(5)/TiO(2), the addition of M into bauxite results in significant promotion of NO(x) removal efficiency, especially at low temperature. Among the catalysts, Cu/bauxite exhibits wide temperature window over 50–400 °C, strong resistance against SO(2 )and H(2)O as well as good regeneration ability in SCR of NO(x). NO(x) conversion is more than 80% at 50–200 °C, and N(2) selectivity is more than 98%. Cu/bauxite can serve as a promising catalyst in SCR of NO(x).
