Photocatalytic reduction of Ni2+over CdS nanoparticles was studied. It was established that CdS/Ni nanocomposite formed in this reaction has photocatalytic activity in molecular hydrogen evolution from aqueous sodium sulfite solutions. Kinetic regularities of these reactions was studied and their mechanism scheme was proposed.


Key words: photocatalysis, CdS nanoparticles, nickel, metal-semiconductor composites, hydrogen.
