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-n Co0.2RunO3 (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°C) and La0.9Ce0.9Fe0.75 Co0.2Ru0.05O3 (n = 0.05) has better activity in all the samples, the conversion of it is 58.5%. With the reducing gas (CO, C3H6) 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.
