The XRD patterns show that the powders mainly consist of CuFeO2 phase. XPS analyses confirm that the chemical environment of Cu+ and Fe3+. The band gap of the sample is 1.48 eV estimated form UV-vis absorption spectra with the absorption wavelength of 300-700 nm. Photocatalytic degradation of methylene blue has been investigated in a Mg-doped CuFeO2 contained aqueous solution When the solution is exposed to powders under UV light, 98.5% methylene blue can be degraded while 97.5% methylene blue is degraded under visible light irradiation.
