in situ SO2 exposure of Cu-CHA deNOx catalysts

Cu chabazites are effective catalysts for NH3-SCR, however their performance decreases in the presence of SO2. The aim of the proposal is to test SO2 exposure of the samples at...铜菱沸石（Cu-chabazite）是氨选择性催化还原（NH₃-SCR）反应的高效催化剂，但在二氧化硫（SO₂）存在的条件下，其催化性能会出现衰减。本研究提案的目标为测试样品在……条件下的二氧化硫暴露情况。
