The resultant samples were characterized by XRD, EDX, TEM, UV–vis DRS, FT–IR, TGA, PL, Accepted 28 January 2016 and VSM techniques. The photocatalytic activities of the resultant samples were investigated by degra- Available online 1 February 2016 dation of rhodamine B in aqueous solution under visible-light illumination. The results showed that the g-C N /Fe O /Ag CrO (20%) nanocomposite exhibited superior activity.
