Effect of Morphological Modification over g-C3N4 on Photocatalytic Hydrogen Evolution Performance of g-C3N4-Pt Photocatalysts

In this study, the morphological properties of g-C3N4 in g-C3N4-Pt photocatalysts were modified by a simple hydrothermal treatment for photocatalytic hydrogen evolution. addition, modification effect on evolution performance was investigated. The long-time clearly changed morphology building extended melem units with more oxygen functional groups at defect edges units, which evidenced X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and photoelectron (XPS) measurements. different features resulted lower photoluminescence (PL) emission intensity PL spectra smaller semicircle radius electrochemical impedance (EIS) data. This indicates efficient charge separation photocatalyst morphology. Consequently, morphologically showed higher rate due to better efficiency.
