Development of catalytic converter by washcoat of ?-alumina on nickel oxide (Nio) catalyst in FeCrAl substrate for exhaust emission control : proposed study

Automobile exhaust emission control is one of the trending issues in automobile research field. It caused by high pollution such as carbon monoxide (CO), nitrogen oxides (NOx), and hydrocarbons (HC) distributed by automobile especially form diesel engine. These pollutants give a harmful effect to the environment and human health. Therefore, this paper proposed in reviewing methods on fabrication of modified catalytic converter. FeCrAl is used as substrate which treated using ultrasonic bath technique which could improve the exhaust emission control. This metallic catalytic converter used as the replacement of precious metal that have high production cost
