An evaluation of the improved catalytic performance of rGO/GO-hybrid-nanomaterials in photocatalytic degradation and antibacterial activity processes for wastewater treatment: A review

Abstract

Agricultural, residential, and industrial activities all impact the environment, resulting in significant changes, such as global warming and wastewater creation. Pollution of wastewater is a public health hazard. Therefore, it is essential to treat persistent contaminants in water and effluent. Several traditional treatment methods; physicochemical reactions, biological degradation, and oxidative decomposition, have been used to treat water and wastewater, but each has its own set of constraints. The utilization of rGO/GO-based composite systems has been extensively researched as a potential solution to address this problem. Due to the synergistic interactions between various components, the mixed composites exhibit higher activity for redox reactions and photocatalytic processes. Even though rGO/GO-based composites are still in their infancy, the growing number of studies demonstrates their enormous promise in various practical applications. The synthesis of rGO/GO-based composites, including their flexible production and applications in photo-catalytic degradation and antibacterial activity processes, is carefully discussed in this review. The fundamental processes of synergistically increased heterogeneous catalysis performance were examined in depth. Finally, the remaining obstacles and potential for rGO/GO-composites heterogeneous catalysis were discussed.
