摘要

•Good activity in range of 210–420 °C with 100% NO conversion and N2 selectivity.•The special activity due to more surface acid amount and suitable redox ability.•Monodentate nitrate and NH2 species as main active intermediates.•H2O mainly restrains L-H reaction pathway leading to the deactivation of catalyst.
