In this study, a Bi4O5Br2/CdWO4 (BOB/CWO) composite photocatalyst was designed and prepared using convenient hydrothermal method. A detailed investigation carried out on the morphology, specific surface area, structure, optical properties, photoelectric chemical properties of BOB/CWO composite. The CdWO4 nanorods were found to disperse Bi4O5Br2 nanoflowers, their tight contact between resulted in formation heterojunction structure. By analysis band structure two semiconductors, it that worked type II mechanism, effectively improving separation efficiency electron–hole pairs. Therefore, exhibited high performance photocatalytic N2 fixation (PNF) reactions. optimal catalyst presents PNF rate 501 μmol L–1 g–1 h–1 under simulated sunlight irradiation, which 5.7 3.1 times pure Bi4O5Br2, respectively. Under visible-light illumination, sensitized coupling effect boosting reaction could still be observed. findings study are anticipated offer practical knowledge about design synthesis efficient photocatalysts for PNF.

Experimental and theoretical confirmation of CeFeCu trimetal oxide/Bi2O3 S-scheme heterojunction for boosted photocatalytic degradation of sulfamethoxazole and toxicity evaluation

Journal of Cleaner Production, Journal Year: 2023, Volume and Issue: 429, P. 139519 - 139519

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.
