摘要	The selective catalytic reduction of NOx with CO (CO-SCR) has emerged as an effective and economical method for NOx removal, yet challenges remain in achieving high catalytic efficiency and selectivity in the presence of O2, especially at lower temperatures. This study focuses on enhancing CO-SCR performance by designing a RhCo/TiO2/Ti monolithic catalyst with optimized CoOx loading. The catalyst exhibits superior performance due to the strong synergistic interactions between Rh and Co species, which significantly improve the low-temperature NO conversion and overall catalytic efficiency. Characterization analyses, including XPS, DFT, and in situ DRIFTS, confirm that the Rh-Co synergy enhances oxygen vacancy formation and promotes NO dissociation. Additionally, the catalyst demonstrates remarkable resistance to water and sulfur poisoning, further improving its practical applicability. This work enhances the understanding of Rh-Co interactions in CO-SCR, providing insights into designing efficient catalysts for NOx removal and reducing environmental pollutants.
