Effective Strategies, Mechanisms, and Photocatalytic Efficiency of Semiconductor Nanomaterials Incorporating rGO for Environmental Contaminant Degradation

The water pollution problems severely affect the natural resources due to large disposal of dyes, heavy metals, antibiotics, and pesticides. Advanced oxidation processes (AOP) have been developed using semiconductor nanomaterials as photocatalysts for treatment an essential strategy minimize environmental pollution. Significant research efforts dedicated over past few years enhancing photocatalytic efficiencies nanomaterials. Graphene-based composites created by integrating reduced graphene oxide (rGO) into various enable unique characteristics graphene, such extended range light absorption, separation charges, high capacity adsorption pollutants. Therefore, rGO-based improve overall visible-light efficiency lead a new pathway high-performance photocatalysts’ potential applications. This brief review illustrates strategies combining rGO with focuses primarily on modification towards contaminants.
