Metal Nanoparticles on Polymer Surfaces: 5. Catalytic Activity of Colloidal Platinum Films Incorporated in Polystyrene Surface Layer

“…In our previous work [7], we reported the results of tentative experiments into the study of catalytic activity of monolayer ensembles of platinum nanoparticles deposited onto the PS surface. It was established that such a system is a highly effective catalyst of the model reaction of methyl viologen reduction with hydrogen.…”

“…The cationradicals are registered by the appearance of characteristic absorption with a maximum at 600 nm [7]. The reaction proceeds at a fairly low rate (Fig.…”

Photochemically reduced polyoxometalate assisted generation of silver and gold nanoparticles in composite films: a single step route

“…Because these materials exhibit novel combinations of metal particle and polymer properties that are attractive for applications in nonlinear optics [11], photo imaging and patterning [12], glazing elements for sunlight control and magnetic devices [13,14], sensor fabrication [15], antimicrobial coatings [16], and catalysis [17]. The dispersed metal nanoparticles into polymers in non-aggregated form, with small diameters allow the preparation of materials with reduced light characteristic properties for applications as optical filters, linear polarizers, and optical sensors.…”

Polymer-Initiated Photogeneration of Silver Nanoparticles in SPEEK/PVA Films: Direct Metal Photopatterning

“…Fabrication of hybrid systems consisting of metal nanoparticles and organic polymers is of considerable interest. These materials exhibit novel combinations of particle and polymer properties that are attractive for applications in nonlinear optics, photoimaging and patterning, glazing elements for sunlight control and magnetic devices, , sensor fabrication, and catalysis …”

“…These materials exhibit novel combinations of particle and polymer properties that are attractive for applications in nonlinear optics, 1 photoimaging and patterning, 2 glazing elements for sunlight control and magnetic devices, 3,4 sensor fabrication, 5 and catalysis. 6 Efficient light-induced formation of metal particles in polymers is a required first step in efforts to develop photoadaptive polymer films and fibers. Earlier studies have shown that formation of Ag crystallites can be achieved with 350 nm photons in films made from blends of poly(vinyl alcohol), PVA, and poly(acrylic acid), PAA.…”
