S-scheme CuInS2/ZnS heterojunctions for the visible light-driven photocatalytic degradation of tetracycline antibiotic drugs

Qingfeng Cui et al.

Summary: In recent years, researchers have been focusing on the wastewater treatment of medical and aquaculture industry, as the antibiotics released from these sources have a detrimental effect on water bodies. In this study, CuInS2/ZnS (CIS/ZnS) heterojunction nanomaterials were prepared and analyzed, and their photocatalytic behavior in the degradation of tetracycline hydrochloride (TCH) under visible light irradiation was investigated. The results showed that the optimized CIS/ZnS(1:2) sample achieved 86% degradation of TCH in 3 hours. The enhanced photocatalytic activity was attributed to the formation of S-scheme heterojunctions and the promotion of charge separation and transportation in CIS/ZnS composite materials. The photocatalytic mechanism was elucidated based on various techniques, including electron paramagnetic resonance, optical properties, and charge/radical trapping experiments. It was found that the CIS/ZnS composite had high stability and could potentially be used as an effective photocatalyst for the removal of hazardous materials from the environment.

Modified-pollen confined hybrid system: A promising union for visible-light-driven photocatalytic antibiotic degradation

Zhiquan Zhang et al.

Summary: In this study, an eco-friendly and highly efficient biohybrid photocatalyst, carbonized rape pollen confined Cu2O nanoparticles (Cu2O/BC), was fabricated for the photodegradation of tetracycline under visible-light illumination. The Cu2O/BC exhibited excellent photocatalytic activity, with a degradation rate roughly 6.0 and 3.2 times higher than BC and Cu2O, respectively. The enhanced performance was attributed to the construction of a heterojunction, promoting the effective separation of photogenerated carriers, and the three-dimensional hollow BC providing structural stability for Cu2O. This work provides crucial insights into the utilization of nature-based biological materials in efficient antibiotic removal and environmental remediation.
