One of the main reasons for this is the high exhaust emission level from Compression Ignition engine based automobiles. At some places including India, the movement of automobiles has been restricted to odd or even days. So, an effective measure is required to prevent this hazard. One of the effective methods for reduction of exhaust emissions from the Compression Ignition engine based automobiles is the use of nano-coated catalytic converter. There are many nano-materials which have been used for various applications including prevention of exhaust emissions from automobiles. This research paper is focussed on the comparative analysis of various nano-materials used in catalytic converter. It will open a pathway as to which catalyst can be more effective for use in the catalytic converter for automobiles based on C. I. engine. Copyright@ International Science Community Association
