Abstract
Due to increased lifestyle of human being, now a day’s demand of automobile is increasing day by day. The major source of air pollutions are from automobiles i. e. from internal combustion engine. Exhaust emission from these engines such as unburnt hydrocarbons, oxides of carbons, and oxides of nitrogen are more harmful for health of living beings and also environment on earth. Hence, throughout the world, efforts are taken to reduce emission level. In present study, an effort was made towards finding an alternate solution for non-noble metal in catalytic converter and various different nanomaterials which can be coated on converter. Catalytic converter with coating of nanomaterial shows a considerable reduction in harmful emission. Results reveal that emission of NOx, HC, CO, CO2 reduces approximately by 31%, 20%, 03% and 21% respectively.
