Construction of novel nanocomposite based on the reduced graphene oxide/metalation of porphyrin for photocatalytic process by real sample analysis and antimicrobial applications

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 Staphylococcus aureus. The findings demonstrate that the rGO/Cu-Por nanocomposite displayed significant antimicrobial activity with great zone of inhibition values.
