Fabrication of noble-metal-free NiS2/g-C3N4 hybrid photocatalysts with visible light-responsive photocatalytic activities

Nanocomposites of NiS2 with graphitic carbon nitride (NiS2/g-C3N4) have been successfully synthesized by means of a facile hydrothermal method. The photocatalytic activities of as-prepared samples were evaluated by monitoring the photodecomposition of rhodamine B under visible light irradiation. The experimental results indicated that visible light-driven NiS2/g-C3N4 composites exhibited an enhanced photocatalytic activity compared to that of...
