摘要：

Hydrogen production from water splitting via photocatalytic reactions can be an alternative clean energy of fossil fuels in the future. Graphitic carbon nitride (g-C3N4) is one of the active photocatalysts in the visible light region that can be combined with other semiconductors in order to increase its photocatalytic efficiency. TiO2 is one of the most appropriate choices to combine with g-C3N4 because of its conduction band edge and variety forms of nanostructures. In this work, nanosheets of g-C3N4 were mixed with the nanoparticles of titanate in order to enhance charge separation and photocatalytic efficiency. Consequently, the hydrogen evolution of this novel nanocomposite produced almost double hydrogen in comparison with g-C3N4.
