Abstract

Manganese oxide (MnOx) catalysts have emerged as efficient agents for simultaneous removal of nitric oxide (NO) and carbon monoxide (CO) from industrial emissions at low temperatures, contributing significantly to environmental remediation efforts. However, the presence of potassium salts, prevalent in biomass-derived fuels, poses a substantial challenge to their catalytic performance. Potassium ions (K+) interact with MnOx catalysts, leading to catalyst deactivation, surface poisoning, and altered reaction pathways. This abstract explores the mechanisms through which potassium salts impair MnOx catalysts, drawing upon experimental evidence and mitigation strategies. Understanding these interactions is crucial for advancing catalyst design and operational practices to enhance the sustainability and efficacy of NOx and CO emission control technologies in industrial settings.
