Abstract:

Silver-graphite carbon nitride (Ag/g-C3N4) was designed and synthesized through a simple and cost effective green chemical route. Structural and morphological features of the Ag/g-C3N4 photocatalyst was comprehensively characterized by Fourier transform infra-red (FT-IR), X-ray diffraction (XRD), high-resolution transmission microscopy (HR-TEM), energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) and the specific surface area was calculated from Brunauer-Emmett-Teller (BET) analysis. The HR-TEM and XRD results indicate that the synthesized Ag nanoparticles, spherical like nanoparticles with an average size of ~6 nm were randomly loaded on the surface of g-C3N4. Graphitic carbon nitride (g-C3N4) is a well-known semiconductor material with a graphite-like layered structure. It has been used extensively in electrochemical water splitting and as a photocatalyst for hydrogen generation and pollutant degradation due to its band gap energy (~2.7 eV), high thermal and chemical stability, non-toxicity, easy preparation, abundance, and environmental benignity. In addition, the Ag/g-C3N4 nanocomposites exhibited 2.5 times higher photocatalytic activity than pristine g-C3N4 for the degradation of malachite green (MG) dye under UV-light irradiation.
