Photocatalytic degradation of pharmaceutical pollutants in water or wastewater is becoming a hot topic for environmental clean-up. Herein, novel CeFeCu trimetal oxide (CFC TMO)/Bi2O3 (CFCB) photocatalysts were prepared through precursor mixing, ultrasonication, and calcination methods used photocatalytic sulfamethoxazole (SMZ). The pseudo-first order kinetic rate CFCB-2 catalyst on SMZ reached 0.0577 min−1 which 4.93 10.02 times higher than α-Bi2O3 CFC TMO under visible light illumination. This was proved by the strong interaction between pristine materials as confirmed XPS density functional theory (DFT) calculations. DFT calculations indicated that having more orbital distribution could make it easier to capture electrons produce radicals electron transfer. Meanwhile by-products showed no sign cytotoxicity towards human embryonic kidney cell line (HEK 293) intestinal epithelial (CACO-2). findings scavenger experiments ESR measurements •OH •O2− played superior role decomposition SMZ. Furthermore, S-scheme charge carrier transfer pathway are proposed analysed. study paves ways into promising strategy construction based heterojunction decontamination can be extended other applications such Fenton-like reactions persulfate activation.

Extracting functional materials from industrial waste residues to absorb organic dyes can maximize reuse and minimize water pollution. However, the extraordinarily low purification efficiency still limits practical application of this strategy. Herein, lamellar NiOOH is in-situ anchored on red mud surface (ARM/NiOOH) as an adsorbent purify in wastewater. ARM/NiOOH with high specific area porosity provides considerable active sites for congo (CR), thereby significantly enhancing removal CR. Besides, we fit a reasonable adsorption model investigate its kinetics. Resultantly, remarkably adsorb 348.0 mg g−1 CR within 5 min, which 7.91 times that raw RM. Our work strategy reusing purifying sewage pollution, advances wastewater treatment engineering.
