NiMnTi mixed metal oxide (NiMnTi-LDO) was novelly fabricated via calcining NiMnTi layered double hydroxide. The structure and property of as-prepared sample were investigated by multiple characterizations and the results revealed that NiMnTi-LDO possessed high surface area, fine dispersion, strong reducibility and abundant surface acidic sites. The catalytic performance of NiMnTi-LDO catalyst was evaluated in selective catalytic reduction of NOx with NH3 (NH3-SCR). The catalyst displayed preferable NOx conversion of above 90% and N-2 selectivity in a broad temperature range of 180-360 degrees C. Moreover, the resistance to SO2 and stability were favorably attained at 210 degrees C over NiMnTi-LDO catalyst. [GRAPHICS] .
