Abstract
The Ag/Co2O3/g-C3N4 as a novel nanocomposite was synthesized using a facile strategy by “one pot” method. The as-prepared nanocomposite was applied to improve the antibacterial effect against Escherichia coli and Staphylococcus aureus bacteria. The nanocomposite was characterized by Fourier transform infrared spectroscopy, X-ray Diffraction, and Scanning Electron Microscopy techniques. The strong interaction beetween the plans of graphitic carbon nitride (g-C3N4) and other particles can be resulted to stable nanocomposite. The zone inhibition of nanocomposite was determined for Gram-positive and Gram-negative bacteria. The findings showed the better activity of as-prepared nanocomposite against Gram negative bacteria rather to Gram positive bacteria. The Ag/Co2O3/g-C3N4 was shown good antibacterial effect compared to g-C3N4 and Ag patricles. Further, Colony Forming Unit was indicated the antibacterial behavior of as-prepared composite. The present study can explain insight into the synthesis of heterojunction composite for disinfection.
