载体涂层对负载型NiMnO3钙钛矿催化剂催化燃烧VOCs性能的影响
Effect of support coating on the catalytic performance of supported NiMnO3 perovskite catalysts
摘要
Abstract
NiMnO3 perovskite catalysts supported on cordierite honeycomb were synthesized by the citric acid method using Ni(NO3)2·6H2O and Mn(NO3)2. The effect of the coating on the catalytic performance of VOCs in catalytic combustion was investigated. These catalysts were characterized by XRD,SEM,BET,and H2-TPR. The results indicate that the different coating has different effects on the NiMnO3 perovskite catalysts. The Ce0.75Zr0.25O2 coating helps to improve carrier’s specific surface area and the active ingredient’s high temperature stability,and the load is more uniformly dispersed, while the grain size becomes smaller. At the same time,the synergistic effect between Ce0.75Zr0.25O2 coating and NiMnO3 perovskite catalysts can improve the Redox cycle rate of the reaction,and further improve the catalytic performance of the catalysts.关键词
