Photocatalytic degradation of Tetracycline under visible light irradiation by Ag-ZnS/rGO

What is it about?

Of the various types of antibiotics, Tetracycline (TC) is the second most commonly used antibiotics regarding its worldwide production and consumption. The presence of such antibiotics in the environment, including the aquatic environment, can cause various reactions from simple allergies to direct toxicity in some cases. Accordingly, it is necessary to provide an efficient system to eliminate such compounds from the aquatic environment, as the conventional wastewater treatment and water refinery processes are unable to completely decompose and eliminate such sustainable compounds. Photocatalytic processes turn out to be one of the most appealing solutions considering their ability to degrade a wide range of organic compounds.

Why is it important?

The performance of photocatalytic processes is based on the simultaneous use of the catalyst and irradiation source (without the requirement for sophisticated equipment), where it is important to use efficient catalysts and cost-effective irradiation sources (such as visible light irradiation). Metal sulfides are among the suitable compounds to be used as catalysts, which are of great importance because of their sustainability within chemical reactions and their economic and practical features.
