| Abstract: | The photocatalytic activity of ZnS nanoparticles during the reduction of the KAu(CN)2 complex was found. The spectral characteristics of the nanocomposite ZnS/Au0 and also the principal kinetic relationships involved in its formation were studied. It was shown that the photoreaction
has equilibrium character resulting from oxidation of the obtained gold by holes in the valence band of the zinc sulfide.
