Abstract

Air pollution is a major environmental threat nowadays. The automotive vehicles and stationery (industry) sources, producing pollutants such as soot, CO, CO2, and NOx, are the major cause of it. Various health issues such as cardiovascular disease, inhaling problems, and eye irritation are caused by these pollutants. The controlling of pollutants is necessary to protect the environment and human beings. In this study, a comparative analysis of silver-doped ceria, silver-doped zirconia, silver-doped silica, and silver-doped alumina catalysts has been discussed based on their structural property, surface contact property, the effect of size on reactivity, and methods of preparation. Silver-based materials provide low-temperature combustion of soot, high thermal stability, and good surface contact property to the catalyst and it is economical than Pt and Au which are being effectively used for soot combustion activity.
