Nanomaterials-based advanced oxidation processes for wastewater treatment: A review

Abstract

Over the past decades, advanced oxidation processes (AOPs) for wastewater treatment drawn a great deal of attention of the researchers. AOP’s are one of the promising advanced technologies to destroy the total organic content, toxic pollutants etc. from the wastewater. A number of attempts has been made from the past two decades on the waste water treatment using various advanced oxidation treatment techniques. The main objective of this review article is to provide the quick reference for researchers and academicians in the area of wastewater treatment using nanomaterials in conjunction with various AOPs and/or hybrid AOPs. This review article is mainly focused on (1) the nanomaterials-based individual and hybrid AOPs for treatment of various industrial effluents or model effluents, (2) the current status of work in the area of hybrid nanomaterials as heterogeneous catalysts combined with AOPs and hybrid advanced oxidation processes.
