Advanced Oxidation Processes for Wastewater Treatment: Perspective Through Nanomaterials

The advanced oxidation processes (AOPs) are an important development for wastewater purification systems. AOPs are capable of degrading the complete organic compounds present in wastewater. In the past few decades, main attention has been given on nanomaterials involving AOPs/hybrid AOPs. The idea of this study is to lay out a quick map of wastewater treatment through nanomaterials in correlation with AOPs and hybrid AOPs, along with recent innovations in process intensification for effective removal of organic pollutants. In support of the importance of ·OH radical in AOPs, a special attention has also been given to its mechanistic aspects with photo and nano-photo chemical AOPs.
