Exhaust Gases Pollution Control Using of Bimetallic Nanoparticles and Bimetallic Nanocomposites in Catalytic Converter: A Review

The automotive and chemical reactor application is one of the engineering technologies that can be used to reduce air pollution is the use of catalytic converter mounted on gas exhaust duct. Catalytic converters are employed for reduction and oxidation of toxic gases byproducts produced during the burning of fuels. Unfortunately, these tools are very expensive, because the catalyst was made from expensive metals and rarely available such as Palladium, Platinum and Rhodium. Besides, the catalyst is susceptible to fuel with low levels of lead which results in the loss of the function of the catalyst due to blockage in the basic structure of Catalytic Converter. Therefore research needs to be done in the to test the other substrate materials as a catalyst, to study the ability of the catalyst in a catalytic converter to reduce exhaust emissions of Carbon Monoxide and Hydrocarbon. This research is focusses on the history of development of the catalytic converter and the modifications taken place during the recent past years. This paper also shows the study of various bimetallic nanoparticles and bimetallic nanocomposites as a catalyst and there performance capabilities such a way to obtain the suitable Catalytic Converter.
