“…Therefore, it is imperative to effectively remove TCH from aquatic environments. So far, many technologies have been employed for the treatment of antibiotics effluent, such as flocculation, ion-exchange, adsorption, biochemistry, advanced oxidation, photocatalytic oxidation, − etc. Among these approaches, photocatalytic technology has received considerable attention due to its high efficiency and cleanliness.…”

In this paper, a facile and efficient photocatalytic system for tetracycline hydrochloride (TCH) degradation is proposed. Ce-doped Bi2WO6 (Ce–Bi2WO6) nanosheets rich in oxygen vacancies were synthesized using a simple hydrothermal method and were systematically characterized. The results exhibited that a 10% Ce–Bi2WO6 (BWCe-10) catalyst with thinner and curling nanosheets was rich in oxygen vacancies, and the band gap was narrowed from 2.78 eV (Bi2WO6) to 1.61 eV, which was conducive to enhancing the photocatalytic activity of BWCe-10. As expected, BWCe-10 nanosheets exhibited much higher photocatalytic performance with 61.1% degradation of TCH within 40 min due to the formation of oxygen vacancies. Moreover, the addition of H2O2 further enhanced the TCH degradation efficiency and yielded a removal rate of 90.4%, revealing a strong synergistic effect between oxygen vacancies and H2O2 in the BWCe-10/H2O2/light system. As an electron acceptor, H2O2 boosts the separation rate of the photogenerated carriers, thereby improving the photocatalytic activity. Furthermore, the potential applications of the BWCe-10 nanosheet in terms of the effect of coexisting ions, stability, and universality were investigated. In addition, possible degradation mechanisms and pathways were proposed. In this system, h+ and e– played important roles in TCH degradation and followed the sequence h+/e– > •O2 – > •OH, and the formation of •OH and •O2 – was proved by ESR analysis. This simulated sunlight-driven system offers insights into the degradation of organic contaminants.

“…However, its bulky structure often leads to high charge carrier recombination, which severely inhibits the PHE efficiency of CdIn 2 S 4 and hinders its practical application. To address this issue, the scientific community has developed many heterostructured composite materials, in which the internal electric field (IEF) facilitates the separation and migration of photoinduced carriers. − For example, many CdIn 2 S 4 -based composite photocatalysts, such as TiO 2 /CdIn 2 S 4 , UiO-66/CdIn 2 S 4 , ,, and ZnIn 2 S 4 /CdIn 2 S 4 , ,, have been developed and have shown remarkably enhanced photocatalytic performances. Thus, constructing CdIn 2 S 4 -based heterojunction photocatalysts is an efficient strategy to improve PHE activity.…”
