Highly effective NO decomposition by in situ removal of inhibitor oxygen using an oxygen transporting membrane

摘要

Due to the in situ removal of the inhibitor oxygen using an oxygen transporting membrane, a complete conversion of NO to N_2 was achieved for the first time in a catalytic perovskite membrane reactor.rnNitrogen oxides (NO_x, x = 1,2), which are mainly produced by automobiles and stationary power plants, are among the major atmospheric pollutants. Several methods have been employed to reduce NO emission, such as non-selective catalytic reduction (NSCR), selective catalytic reduction (SCR) with NH_3 or hydrocarbon, and direct catalytic decomposition of NO.
