Efficient treatment for oily wastewater via photo‐Fenton‐like processover NdFeO 3 perovskite: Effect of calcination temperature

Abstract NdFeO 3 (NFO) nanoparticles were synthesized by a facile hydrothermal method, followed by calcination treatment at various temperatures. The NFO samples were systematically characterized using X‐ray diffraction, Thermogravimetric, Fourier transform infrared spectra, UV‐vis diffuse reflectance spectroscopy, Transmission electron microscopy, and N 2 adsorption‐desorption analysis. The visible‐light photocatalytic performance of different calcined temperature NFO was examined by the photodegradation of oily wastewater. The results revealed that NFO nanoparticles calcined at 800 °C exhibited the highest photocatalytic activity when 0.3 g/L of H 2 O 2 was added during the photocatalysis, suggesting that NFO could be a promising photo‐Fenton catalyst for decomposing organic contaminants in wastewater.
