Resumen

g-C₃N₄/NiS photocatalyst synthesized using a two-step procedure involving thermal condensation and solvothermal techniques. The presence of two phases in the hybrid material obtained was observed in the results of XRD and XPS analysis. The UV spectroscopy analysis of g-C₃N₄/NiS showed a shift to lower energies in the adsorption region comparing to bare g-C₃N₄, with values band gap values of 2.74 and 2.3 eV, respectively. The SEM analysis showed the typical g-C₃N₄ lamellar morphology with clusters of NiS grown over g-C₃N₄. The yield of H₂ obtained with the hybrid material in the water splitting reaction under UV irradiation was 30% higher than that obtained when pure g-C₃N₄ was used as photocatalyst.
