“…To effectively degrade ibuprofen, researchers have used a number of methods to try to remove this contaminant, including adsorption, electrocatalysis, photocatalysis, thermal catalysis, and biodegradation ( Navrozidou et al, 2019 ; Falletta et al, 2023 ; Abdo et al, 2024 ; Jin et al, 2024 ; Li et al, 2024 ). Among these methods, photocatalysis is a green technology that degrades ibuprofen only with the help of light energy ( Sruthi et al, 2021 ; Rebollo et al, 2024 ). Although it is said that light energy is required, the degradation of ibuprofen cannot be completed without a photocatalyst ( Shakir, 2024 ).…”

The oxalic acid complexation method and sulfuric acid heat treatment method were used to synthesize the YMnO3 (YMO) and YMO-SO42- (YMO-SO) photocatalysts. The YMO-SO photocatalyst maintained the crystal structure of YMO, but the particle size increased slightly and the optical band gap decreased significantly. The YMO-SO photocatalyst demonstrates a wide range of light absorption capabilities, covering ultraviolet, visible and near-infrared light. The photocatalytic activity of YMO-SO was investigated with ibuprofen as the target pollutant. The YMO-SO photocatalyst exhibits high ultraviolet (UV), visible and near-infrared photocatalytic activity. Experiments with different environmental parameters confirmed that the best catalyst content was 1 g/L, the best drug concentration was 75 mg/L and the best pH value was 7. The capture experiment, free radical detection experiment and photocatalytic mechanism analysis confirmed that the main active species of YMO-SO photocatalyst were hole and superoxide free radical.
