- Abstract
- The mitigation of polycyclic aromatic hydrocarbons (PAHs) in the aqueous environment by physical and biological processes is a considerable challenge. Among various remediation approaches, heterogeneous photocatalysis is considered an efficient and eco-friendly option to convert PAHs into less harmful and/or biodegradable end products. This review provides a comprehensive overview of various nanophotocatalysts used to degrade PAHs in water based on their photocatalytic performances (e.g., in terms of quantum efficiency, space-time yield (SY), and figure-of-merit). Among photocatalysts, semiconductor metal oxides (e.g., TiO2 and ZnO) and noble metal-doped graphene composites are identified as the most effective options due to their high photoactivity, low-cost, and tailorable structural/functional characteristics. The present and futuristic challenges in the development of photodegradation of PAHs in aqueous medium are also discussed to deliver a blueprint to construct high performance photocatalysts for their removal.
