Study on the catalytic mechanism and water resistance of Cu-Mn-Snx 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...

| description | 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 (Oads) and surface lattice oxygen (Olat) in O 1s, which is the reason for the improved activity of the Cu-Mn-Sn catalyst. Sn weakens the coordination bond between Cu2+ and H2O, reducing the formation of CO3 2−, which is the reason for the improved water resistance of the catalyst. |
