Volatile organic compounds (VOCs) and carbon monoxide (CO) are widely recognized as hazardous air pollutants due to their dangerous effects on both human health and the environment. Exposure to these compounds is associated with respiratory disorders, cardiovascular diseases and atmospheric pollution phenomena. Consequently, the development of efficient technologies for their removal represents a critical objective in the field of environmental catalysis. The present work focuses on the investigation of the catalytic oxidation of two representative pollutants: carbon monoxide, produced from incomplete combustion processes, and ethylene, chosen as a representative VOC to evaluate catalyst performance toward hydrocarbon oxidation. Catalytic oxidation was selected due to its ability to convert harmful compounds into less toxic products, primarily carbon dioxide and water, under relatively mild operating conditions compared with conventional thermal treatments.
