Abstract
This chapter focuses on the recent progress in the development and application of hybrid 3D Gr for the photocatalytic remediation of organic pollutants such as dye molecules, emerging contaminants, and heavy metals. Various novel design based on semiconductor/3D Gr has led to the creation of highly efficient heterojunction photocatalyst. In addition, the authors have also made an effort to discuss some photocatalytic anti-bacterial disinfection innovations. Finally, prospects in the construction of hybrid 3D Gr possessing enhanced photocatalytic materials are presented. This write-up should provide a comprehensive overview of hybrid 3D Gr architecture in wastewater remediation applications. Photocatalysis is among the leading green strategy in wastewater remediation contaminated with pollutants such as synthetic dye, heavy metals, emerging contaminants, and pathogens. Gr oxide is often used as the starting material for the preparation of the 3D macrostructure ascribed to the ample oxygenated groups present which provide many active sites for interactions.
