EuFeO 3 (EFO) nanoparticles were prepared by sol–gel method with an aid of tartaric acid at different calcination temperatures. The prepared EFO samples were characterized by differential thermal analysis–thermogravimetry, X‐ray diffraction, Fourier transform infrared spectra, Raman spectra, transmission electron microscopy, UV‐visible diffuse reflectance spectrum, N 2 adsorption/desorption measurements, and photoluminescence spectra. The photocatalytic activity of the samples was evaluated by the photocatalytic decolorization of rhodamine B aqueous solution under visible‐light irradiation. The calcination temperature for the highest photocatalytic activity of the EFO nanoparticles was found to be 750°C. Much enhanced photocatalytic activity was observed when adding a small amount of H 2 O 2 during the photocatalysis, indicating EFO nanoparticles have photo‐Fenton‐like catalytic activity. EFO nanoparticles were further demonstrated to have an excellent photocatalytic stability, which is useful for the efficient recovery of photocatalyst.
