REDOX REACTION OF NITRIC-OXIDE AND CARBON-MONOXIDE OVER CUO-V2O5 SYSTEM

Modern industrialisation and enormous increase of automobiles account high degree of atmospheric pollution. Transportation based on fossil f uel combustion alone is a major source of air pollution, emitting noxi ous gases like carbon monoxide, nitrogen oxides, unburned hydrocarbons among other species. The conversion of toxic gases into non-toxic pro ducts before discharging in the atmosphere, with suitable catalysts, i s highly desired. Some countries have developed catalytic converters c onsisting of noble metals like platinum and platinum-palladinium alloy s(1), which are not economical to the developing countries. Therefore, cheaper catalyst which can withstand high temperature and free from p oisoning, is needed as substitute of the expensive automotive exhausts platinum catalyst.
