Overview of thesis

My thesis is based on novel remediation technologies using macroscopic graphene-based materials for wastewater treatment. The aim of this study is to synthesis non-metallic catalysts based on graphene for the oxidation of emerging organic contaminants in wastewater. In the traditional advanced oxidation processes (AOPs) catalyst recovery and reusability has posed a great challenge. Herein, this shortcoming has been overcome by nanoengineering and structural modification of 2-dimensional graphene to 3-dimensional graphene. The as-synthesised catalysts are then applied in the wastewater treatment technologies under both continuous reaction and batch reaction systems. Further, chemical reaction kinetics are studied and analysed to develop on optimal reaction system which could be potentially applied in the commercial wastewater remediation systems.
