Mesoporous chromium oxide (Cr2O3) nanocrystals were first synthesized by the thermal decomposition reaction of Cr(NO3)3·9H2O using citric acid monohydrate (CA) as the mesoporous template agent. The texture and chemistry of chromium oxide nanocrystals were characterized by N2 adsorption−desorption isotherms, FTIR, X-ray diffraction (XRD), UV−vis, and thermoanalytical methods. It was shown
