Efficient treatment for oily wastewater via photo‐Fenton‐like processover NdFeO3 perovskite: Effect of calcination temperature

NdFeO3 (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 N2 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 H2O2 was added during the photocatalysis, suggesting that NFO could be a promising photo‐Fenton catalyst for decomposing organic contaminants in wastewater. NdFeO3 (NFO) nanoparticles were prepared by a facile hydrothermal method and used as an effective heterogeneous photo‐Fenton catalyst for the degradation of organic pollutants in oily wastewater. The various calcination temperatures were found to have a significant impact on the structure, optical properties, and photocatalytic activity of the NFO nanoparticles. The sample calcined at 800 °C exhibited the highest activity for the degradation of hydrocarbons in oily wastewater and could maintain good activity after four cycles of reuse.
