Abstract:
The simultaneous removal reaction (SRR) is a pioneering approach for achieving the simultaneous removal of anthropogenic NO and CO pollutants through catalytic reactions. To facilitate this removal across diverse industrial fields, it is crucial to understand the trade-offs and synergies among the multiple reactions involved in the SRR process. In this study, we developed mixed metal oxide nanostructures derived from layered double hydroxides as catalysts for the SRR, achieving high catalytic conversions of 93.4, 100, and 91.6% for NO, CO, and NH3, respectively, at 225 °C. Furthermore, we elucidated the reaction mechanisms, revealing the trade-offs and synergies between the multiple reactions. In addition, we fabricated sheet-type catalysts and conducted SRR tests in a semibench-scale reactor with a gas flow rate of 10 L min-1 at 1% CO concentration. The fabricated catalysts exhibited high SRR activity and stability, even in the presence of SO2, highlighting their potential for practical applications.
