Abstract

A series of silver-containing composites based on highly hydrophilic silica S-120, moderately hydrophilic activated carbon, and hydrophobic copolymer of styrene with divinylbenzene (Psb-1) is synthesized and studied using nonlinear gas chromatography, XRD, IR spectroscopy, and volumetric adsorption, and by optical means. The effect modifying an adsorbent with silver nanoparticles has on the structure, geometry, and chemistry of its surface, and the effects the concentration of metal, the nature of the matrix, the means of synthesis, and the size of nanoparticles have on its adsorption and catalytic properties, are studied. The surface plasmon resonance (SPR) effect is observed in some composites.
