The main objective of this study is to prepare and combine reduced graphene oxide (rGO) with copper-5,15-bisdodecylporphyrin (Cu-Por) nanoparticles in order to produce a unique rGO-loaded Cu-Por nanocomposite. Characterization techniques such as scanning electron microscopy (SEM), Raman spectroscopy, X-ray diffraction (XRD), X-ray photoelectron absorption spectroscopy (XPS) and ultraviolet-visible (UV-Vis) spectroscopy were utilized to analyze the structure of the synthesized rGO/Cu-Por. The effectiveness of the resulting rGO/Cu-Por nanocomposite as a catalyst was evaluated based on several parameters, such as pH, the initial concentration of the MR dye, and the amount of nanocomposite employed. Remarkably, a quantity of 20 mg of the rGO/Cu-Por nanocomposite demonstrated a significant removal efficiency of 99.7% for MR at a pH level of 3.5. The actual sample exhibited a degradation amount of 69.21%. In addition, the antimicrobial efficacy of the nanocomposite was assessed against the G-negative and the G-positive bacterium. The findings demonstrate that the rGO/Cu-Por nanocomposite displayed significant antimicrobial activity with great zone of inhibition values.

The development of cost-effective and high-performance technologies for wastewater treatment is essential for achieving a sustainable economy. Among the various methods available for water remediation, adsorption is widely recognized as an effective and straightforward approach for removing a range of pollutants. Gel materials, particularly hydrogels and aerogels, have attracted significant research interest due to their unique properties. Hydrogels, for instance, are noted for their ability to be regenerated and reused, ease of separation and handling, and suitability for large-scale applications. Additionally, their low cost, high water absorption capacity, and contribution to environmental protection are important advantages. Aerogels, on the other hand, are distinguished by their low thermal conductivity, transparency, flexibility, high porosity, mechanical strength, light weight, large surface area, and ultralow dielectric constant. This review provides a comprehensive analysis of the current literature, highlighting gaps in knowledge regarding the classification, preparation, characterization, and key properties of these materials. The potential application of hydrogels and aerogels in water remediation, particularly in removing contaminants such as dyes, heavy metals, and various organic and inorganic pollutants, is also discussed.
