Abstract:
A method for the synthesis of nonstoichiometric silver sulfide nanoparticles which are catalytically active under visible light irradiation (450 nm) has been suggested and explored. The photocatalysts were characterized by UV–vis spectroscopy, high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and low-temperature N2 adsorption–desorption techniques. The catalytic activity of nonstoichiometric silver sulfide nanoparticles was measured by the photocatalytic evolution of hydrogen from the aqueous solution of Na2S/Na2SO3. High photocatalytic activity is measured for all samples with excess of silver nanoparticles. Higher photostability of nonstoichiometric silver sulfide nanoparticles stabilized by EDTA in compare to non-stabilized nanoparticles were found. This effect can be explained by nonstoichiometry and crystalline silver impurities on the surface of stabilized silver sulfide nanoparticles.
