The Preparation of g-C3N4/ZnO for Degradation of Ofloxacin under Visible Light Irradiation

Abstract

The presence of non-biodegradable antibiotics in wastewater can lead to antibiotic pollution which has negative impacts on the environment and living organisms. Hence, it is important to discover a technique for removing hazardous organic contaminants and antibiotics in water bodies. The use of g-C₃N₄ photocatalyst in heterogeneous photocatalysis for advanced oxidation process (AOP) has gained significant attention in recent years for wastewater treatment. Nevertheless, ZnO and g-C₃N₄ have several limitations such as high recombination rate of electron-hole (e^-/h⁺) pairs and limited light absorption within the range of solar spectrum, respectively. These factors can reduce its photocatalytic activity.
