“…The presence of adsorbed water is mainly due to the absorption of water by the sample during storage and the use of potassium bromide during testing. The peaks at 627 and 468 cm -1 can be ascribed to the Y-O stretching and Mn-O-Mn bending vibrations, respectively ( Zhang and Wang, 2017 ; Shukla et al, 2023 ). In addition, a new characteristic peak at 1,117 cm −1 appeared in the YMO-SO sample.…”

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.
