Abstract

Crumpled cuprous oxide anchored graphitic carbon nitride (Cu 2O-g-C 3N 4) nanosheets were synthesized for photosplitting of water under visible light illumination. The nanosheets were characterized by scanning and transmission electron microscopies, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Fourier Transform Infrared (FT-IR) spectroscopy. The analytical data showed that the surface of g-C 3N 4 nanosheets crumpled as a result of Cu 2O anchoring. The water photosplitting experiments, performed in the presence of a sacrificial agent methanol, showed the liberation of a significant amount of hydrogen, viz., 842 μmol h −1 g −1 after 48 h illumination. Such superior photocatalytic activity may be due to efficient inter-particle charge transfer in the direction from n-type g-C 3N 4 to p-type Cu 2O which hinders the electron-hole recombination.
