摘　　要：简述了类水滑石复合氧化物的制备方法,并对类水滑石化合物为前驱体的复合氧化物作为环境友好催化材料在烟道气脱SO2、NOx方面的研究进行了综述,指出应把研究重点放在类水滑石复合氧化物同时氧化吸附脱SO2和NOx上。The preparation methods for hydrotalcite-like compounds (HTLcs) and application of mixed oxides catalysts, using hydrotalcite-like compounds as their precursor, as new environmentally friendly catalysts in catalytic removal of SO_2 and NOx in flue gas were reviewed. It was pointed out that future efforts should be made on development of HTLcs catalysts that can simultaneously remove SO_2 and NOx by oxidative adsorption.
