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

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.

Automated summary

Agricultural, residential, and industrial activities have negative impacts on the environment, leading to significant changes such as global warming and wastewater pollution. The pollution of wastewater poses a risk to public health, thus necessitating the treatment of persistent contaminants. While traditional methods have limitations, the use of rGO/GO-based composite systems has shown promise in addressing this issue. These composites exhibit higher activity for redox reactions and photocatalytic processes due to the synergistic interactions between their components.
