Effect of synthesis strategies on morphology and antibacterial properties and photocatalytic activity of graphitic carbon nitride (g-CN).

Different morphologies of graphitic carbon nitride (g-CN), including bulk g-CN(B-CN), ultrathin nanosheet g-CN(N-CN), and porous g-CN(P-CN) were synthesized through a facile one-step approach. They were then employed as efficient photocatalysts under visible light to degrade methylene blue and deactivate() and() bacteria. The synthesized powders were characterized using various industry standard techniques and field emission scanning electron microscopy (SEM) analysis successfully represented the various morphologies of g-CN. Furthermore, the antibacterial activities of synthesized samples were examined, and the results revealed that B-CN, N-CN, and P-CN powders could eliminate around 64%, 82%, and 99% ofunder visible light irradiation and about 30%, 56, and 67% in dark conditions. On the other hand, the bacterial reduction rate ofwas approximately 61%, 74%, and 99% for B-CN, N-CN, and P-CN powders under visible light irradiation and about 38%, 60%, and 77% in dark conditions. The SEM analysis revealed that P-CN causedandbacteria to rupture, completely separating their internal contents from the cell membrane. g-CNphotocatalytic antibacterial agents can be utilized as a unique potential solution for nosocomial infection management.
