Effects of SiO2, Al2O3 and TiO2 Catalyst Carriers on CO-SCR Denitration Performance of Bimetallic CuCe Catalysts

Year: 2025

Type: article

Abstract: Nitrogen oxides (NOx) emissions pose environmental and health risks. Selective catalytic reduction (SCR) is effective for NOx removal, and using CO as a reductant can eliminate both NOx and CO. This study explores CuCe catalysts on SiO2, Al2O3, and TiO2 for CO-SCR. Results show catalytic activity relates to the synergy between lattice oxygen and CuCe species. TiO2 enhances this interaction, promoting Cu+ and lattice oxygen for NO adsorption and dissociation. The CuCe/TiO2 catalyst achieves 100% NO conversion at 300 °C and 40.2% at 100 °C, indicating excellent low-temperature performance. These findings are valuable for developing efficient SCR catalysts.
