Photocatalytic degradation of phenolic pollutants by Nanocomposites: A systematic review and pooled analysis

All living things depend on water, which is a precious natural resource. Modern hydropower generation, industrial processes, and transportation increasingly rely significantly on water. Emerging contaminants are currently posing a serious threat to our environment and significantly damaging human health. To address these water-related problems, photocatalysis, one of the advanced oxidation processes, has drawn a lot of attention. The most common photocatalytic approach for the elimination of phenolic pollutants, which is one of the emerging pollutants in the aquatic environment, was determined through a systematic review of the scientific literature in the current study. Furthermore, It was thought about how independent variables like pollutant concentration, catalyst amount, radiation time, pH, and contact time might affect the process. Twelve research, all of which focused on phenolic contaminants, were included. In two studies, all 12 phenolic contaminants were eliminated. Most of the pollutants exhibited a degradation efficiency above 90%. The removal of organic contaminants from water can be accomplished with efficiency and effectiveness by using sophisticated photocatalytic treatment methods. However, the combined data support photocatalytic treatment procedures as a new technique in recent years for the removal of organic contaminants.
