The catalytic property of spinel MgCr2O4 was widely studied for combustion oxidation of the organic compound. The catalytic and photocatalytic activity of the MgCr2O4 powder at room temperature were studied in this work. The experiments revealed that the powder has a slow decomposition of methyl orange in dark and fast reductive photocatalytic degradation in light irradiation of 40W-fluorescent lamp. High initial pH of the solution is favorable for reducing decomposition of methyl orange either in dark or in light irradiation. The present article discusses some important patents related to the catalysis of Mg-containing spinel compounds.
