Copper Chromite

Copper chromite is a black powder and inorganic pigment thatadopts a spinel crystal structure. It can be made by the high-temperaturecalcination of copper(II) oxide and chromium(III) oxide or the thermaldecomposition of copper chromate, which evolves oxygen at higher temperaturesand decomposes to copper chromite. The copper chromite is one of the most efficient materials, has wide commercial application as catalysts being used in the unit processes of organic synthesis such as hydrogenation, dehydrogenation, hydrogenolysis, oxidation, alkylation, cyclization, etc. It can be used in the pollution abatement as the catalyst to remove aqueous organic wastes, volatile organic compound and vehicular primary emissions such as CO, unburned hydrocarbon, NOx and soot.
