Abstract
The method for the preparation of stable aqueous dispersions of CdS nanocrystals synthesized by the thermal decomposition of cadmium oleates in the presence of sulfur due to surface functionalization by cationic comb-shaped copolymer of 2-(methacryloyloxy)ethyltrimethylammonium methyl sulfate and stearyl methacrylate is presented. The hydrophilization of the CdS nanoparticles does not noticeably change their size, phase composition, and optical characteristics. The functionalized particles exhibit photocatalytic activity in the reaction of water splitting, which strongly depends on the content of the Pt cocatalyst.
