Descrição geral
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.
Aplicação
Copper chromite is primarily used as a catalyst for hydrogenation reactions because of its ability to hydrogenate functional groups in aliphatic and aromatic compounds selectively. Industrially, copper chromite is used to reduce furfural to furfuryl alcohol[1] and butyraldehyde to 1-butanol,partially reduce conjugated dienes to monoenes, and selectively reduce carbonyl groups in vegetable oils. This CuCr catalyst is studied for a variety of catalytic applications including converting the hydrogenolysis of cellulose[2].It is also used as a catalyst for combustion to help control burn rate and as alight-absorbing pigment. Copper chromite/graphene oxide nanocomposite canbe used in energy storage applications.

A four-step catalytic process was developed to produce p-methylstyrene from methylfuran, a biomass-derived species. First, methylfuran was acylated over zeolite H-Beta with acetic anhydride. Second, the acetyl group was reduced to an ethyl group with hydrogen over copper chromite. Third
