摘要 锰基催化剂具有较高的催化活性,且成本低,在选择性催化还原(SCR)尾气中的NOx领域具有广阔应用前景。介绍了锰基低温SCR催化剂处理NOx的最新进展。锰基催化剂可分为两类:锰氧化物催化剂和锰基掺杂过渡金属氧化物催化剂。针对锰氧化物催化剂,主要分析了锰的氧化价态、结晶形态、比表面积以及形态学对催化效果的影响;对于锰基掺杂过渡金属氧化物催化剂,重点分析了掺杂物对催化剂的催化能力、催化温度范围、N2的选择性和抗SO2、H2O毒化能力的影响。最后在总结全文的基础上,展望了锰基催化剂的应用前景。

Abstract: Manganese(Mn) based catalysts have relatively high catalytic activity and low cost, which has been widely used in selective catalytic reduction (SCR) technology for the removal of NOx from flue gas. The recent progress on the Mn-based catalysts for low-temperature SCR de-NOx is systematically reviewed. On this basis, Mn-based catalysts are divided into two categories: single MnOx catalysts and Mn-based multi-metal oxide catalysts. According to single MnOx catalysts, the effects of Mn oxidation state, crystallization state, specific surface area and morphology on catalytic activity are systematically analyzed. For multi-metal oxide catalysts, the various facts dominated by the components of catalysts are summarized from four aspects, improving de-NOx efficiency, extending operation temperature range, enhancing N2 selectivity, and improving resistance to SO2 and H2O. Finally, the application prospect of manganese based catalysts are predicted according to the above summary.
