Photocatalysis as a novel approach for degradation of phenol in wastewater

Abstract

In recent years, photocatalysis has received considerable attention as an alternative for treating industrial wastewater. Of particular interest in this context is the complete photocatalytic mineralization of a variety of organic compounds into harmless products. Phenolic compound is a group of special interest due to its high toxicity which poses a threat to humans, aquatic and microorganism life. Therefore, efficient treatment of industrial wastewater containing such compounds has become of immediate importance. An ideal waste water treatment process will completely mineralize all toxic species present in the waste stream without leaving behind any hazardous residues. This work attempts to evaluate the use of suitable catalysts, catalyst supports and process parameters highlighted by other researchers in the field of photocatalysis. Current photocatalysis work by our research team and future research directions will also be presented.
