- Abstract
The selective catalytic reduction of NOx by CO (CO‐SCR) holds considerable promise as a simple and cost‐effective technology capable of concurrently removing CO and NOx from mobile and stationary sources. This is especially pertinent for industry sectors with high CO emissions, such as the iron and steel industry, making CO‐SCR an attractive solution with significant industrial applicability. However, despite the promising industrial potential of CO‐SCR technology, its widespread adoption is hindered by several factors, most notably the impacts of SO2, H2O, and O2 on catalyst performance and stability. Current research on these limiting factors is not exhaustive, posing challenges for the comprehensive industrial implementation of CO‐SCR technology. Therefore, this review paper focuses on the variables impeding the industrial utilization of CO‐SCR, summarizing existing bottlenecks and emphasizing the urgent need to address the inhibitory effects of O2 on the CO‐SCR reaction, a critical issue in contemporary research. This review aims to clearly articulate the key challenges of CO‐SCR technology and provide direction for future research.
