Abstract
The photocatalytic properties of Cd0.3Zn0.7S modified by nickel sulfide and nickel hydroxide were studied. The obtained samples were characterized by a wide range of experimental techniques including X-ray diffraction (XRD), UV-vis diffuse reflectance spectroscopy (DRS), and high resolution transmission electron microscopy (HRTEM). The photocatalytic activity was measured in the hydrogen evolution from aqueous solutions of Na2S/Na2SO3 under visible light irradiation (λ = 450 nm). The highest photocatalytic activity and apparent quantum efficiency (AQE) were 6.12 mmol h-1 g-1 and 22.1%, respectively. A mechanism of the photoinduced transformations of the photocatalysts containing Ni(OH)2, NiS, and Ni3S2 during hydrogen production was proposed.
