Study on the catalytic mechanism and water resistance of Cu-Mn-Sn_x catalyst for CO elimination.

ABSTRACT: CO in coal mine underground spaces can easily cause casualties among miners. The humidity in coal mines is relatively high, and traditional Cu-Mn catalysts are prone to deactivation. Compared to traditional Cu-Mn catalysts, doping with Sn enhances the activity and water resistance of Cu-Mn catalysts. The Cu-Mn-Sn catalyst was tested using XPS, FTIR, and a self-made Activity Test Experimental System, with partial data processed using the Avantage software. The results show that Sn increases the number of active sites (Cu⁺) on the Cu-Mn catalyst and the proportion of surface adsorbed oxygen (O_ads) and surface lattice oxygen (O_lat) in O 1s, which is the reason for the improved activity of the Cu-Mn-Sn catalyst. Sn weakens the coordination bond between Cu²
