DOI: 10.1021/acs.est.2c09805
Abstract: The complex poisoning of Cu-KFI catalysts by SO2 and hydrothermal aging (HTA) was investigated. The low-temperature activity of Cu-KFI catalysts was restrained by the formation of H2SO4 and then CuSO4 after sulfur poisoning. Hydrothermally aged… read more here.

DOI: 10.1021/acscatal.0c05697
Abstract: A desirable catalyst for efficiently controlling NOx emissions often demands excellent SO2 poisoning resistance. Here, we introduced Ce to modify birnessite-MnO2 to obtain a Ce-MnO2 catalyst with e... read more here.
