Simultaneous catalytic removal of NO and chlorobenzene over Sn–Mn–Ce–Co–Ox double-way catalyst

Mn-based catalysts are often used for catalytic reduction of NO and catalytic degradation of chlorobenzene. In this work, the promotion mechanism of SnO 2 modification was investigated. The activities of Sn–Mn–Ce–Co–O x catalyst were the best when the SnO 2 content was 8%. In the temperature range f...

Description
Summary:Mn-based catalysts are often used for catalytic reduction of NO and catalytic degradation of chlorobenzene. In this work, the promotion mechanism of SnO 2 modification was investigated. The activities of Sn–Mn–Ce–Co–O x catalyst were the best when the SnO 2 content was 8%. In the temperature range from 120 to 330 ℃, the NO conversion was above 90%, and the T 50 and T 90 of CB decreased to 127 ℃ and 183 ℃. The structure of the catalyst was characterized, and it was found that the catalytic effects of SnO 2 on pollutant degradation performance of Sn–Mn–Ce–Co–O x catalyst were mainly as follows: (1) leading to the formation of a large number of Mn 4+ ; (2) increasing the amount of chemisorbed oxygen on the catalyst surface; and (3) improving the redox performance of the catalyst. CHCl 3 , CCl 4 , C 2 HCl 3, and C 2 Cl 4 intermediate products were generated in the catalytic reaction, covering the catalytic site. Graphical abstract
