摘要
Abstract
Iron-based perovskite-type compounds modified by Ru were prepared through sol-gel process to study its catalytic activity of NOx direct decomposition at low temperature and evaluate the conversion of NO under the experimental conditions. The catalytic activity of La0.9Ce0.1Fe0.8-nCo0.2RunO3 ( n = 0.01,0.03,0.05,0.07,0.09)series for the NO, NO-CO two components, CO-HC-NO three components were also analyzed. The catalytic investigation evidenced that the presence of Ru is necessary for making highly activity in decomposition of nitric oxide even at low temperature (400 ℃ ) and La0.9Ce0.9Fe0.75Co0.2Ru0.05O3( n = 0. 05 ) has better activity in all the samples, the conversion of it is 58.5%. With the reducing gas (CO, C3 H6 )added into the gas, the catalyst displayed very high activity in decomposition of NO and the conversion of it is 80% and 92. 5% separately.关键词
