摘要

Pharmaceuticals are one of the persistent emerging contaminants that are ubiquitous in the aquatic environment due to their extensive application as human and veterinary medicines. The ecotoxicity and microbial resistance are considered to be major adverse environmental and health impact of pharmaceuticals even in trace amounts, which raise global concern. The recalcitrant nature of these pollutants restricts the application of the conventional treatment system for their remediation and triggers extensive research on the various advanced oxidation processes as a promising treatment system. Among them, visible-light-assisted semiconductor photocatalysis has significant potential as an efficient, low-cost, and green technology, which can use even solar energy as a clean and sustainable light source. A comprehensive review on the application of various visible light photocatalysts on the degradation of aqueous pharmaceutical pollutants was attempted to highlight their physiochemical properties, reaction mechanism, and catalytic activity in the laboratory- as well as field-scale operations. The challenges and gaps in the current literature have been identified, and recommendations for prospective research opportunities have been placed based on the findings.[GRAPHICS].
