The present work describes preparation of polyurethane foam modified with borohydride. Adsorption of borohydride from alkaline solutions in presence of a cationic surfactant is discussed. The polyurethane foam modified with borohydride possesses reductive ability with respect to Au(III). Possibilities of the new material for synthesis of gold nanoparticles are described. This solid reducting agent is convenient for use in the synthesis of nanoparticles, since it ensures precise dosing of a reductant while desorbed from polymer. Gold nanoparticles can be synthesized both in solution and on the polymer surface by varying reagents concentrations during the preparation of modified polyurethane foam.
