Combustion derived lanthanum chromite (LC) catalyst was prepared by sonicated sol gel combustion method from lanthanum nitrate hexahydrate La(NO3)3.6H2O(LN),chromium nitrate nonohydrate Cr(NO3)3.9H2O(CN),glycine and urea as combination fuel. Nanocrystalline LaCrO3 powder was formed after heating at 165oC for five minutes. Synthesized powder was characterized by using FT-IR, X-ray diffraction, TG-DTA, EDS, SEM. Average particle size of synthesized powder was determined by Debay Scherrer’s equation and was found 28.86 nm. BET surface area of LaCrO3 by flow BET nitrogen adsorption method was found 22.7 m2/g.Photoreactivity of LaCrO3 was studied for degradation of Eriochrome Black T indicator.100% degradation efficiency is achieved at 10 ppm solution,6 volume H2O2 and 8.2 pH in 40 minutes. Reusability of catalyst reveals green nature of catalyst
