The catalytic performance of MnOx-CeO2 for the simultaneous NOx reduction and chlorobenzene (CB) oxidation was investigated. The MnOx(0.4)-CeO2 solid composition exhibited excellent catalytic activity due to the formation of MnyCe1-yO2-δ solid solution and the good balance between redox properties and surface acidity compared to pure ceria. The presence of CB improved both the NOx conversion and N2 selectivity in the range of 200–300 °C. Furthermore, the activity temperature window for NOx reduction was broadened when CB was introduced into the flue gas, and the CB oxidation ability was also enhanced in the presence of O2 and NH3/NO.

的MnO X -CeO 2种催化剂的有效NO X在氯苯的存在下还原

研究了MnO x -CeO 2对同时还原NO x和氯苯(CB)氧化的催化性能。MnO x(0.4)-CeO 2固体组合物由于形成了Mn y Ce 1-y O2 固溶体而具有优异的催化活性,并且与纯二氧化铈相比,氧化还原性能和表面酸度之间具有良好的平衡。在200–300°C范围内,CB的存在改善了NO x转化率和N 2选择性。此外,NO x的活动温度窗口当将CB引入烟气中时,还原作用扩大,并且在O 2和NH 3 / NO存在下,CB的氧化能力也得到增强。
