Organic-inorganic composite materials have attracted great attention because of their potential to combine the features of organic materials with those of inorganic materials. Particularly organic-metal composite such as polymer-silver are promising functional materials in areas ranging from electronic and optical devices to biosensing, antimicrobial agents and catalysis. In general, there are ...

Plasmonic nanoparticles have been increasingly investigated for numerous applications in medicine, sensing, and catalysis. In particular, gold nanoparticles have been investigated for separations, sensing, drug/nucleic acid delivery, and bioimaging. In addition, silver nanoparticles demonstrate antibacterial activity, resulting in potential application in treatments against microbial infections...

This article highlights our recent work concerning the synthesis of metal nanoparticles and their non-ordered superstructures. After a short introduction, the basic synthetic procedures are explained for the nanoparticles used for the assemblies. Furthermore, a fabrication method is itemized for very monodisperse platinum nanoparticles in aqueous solution ranging in diameter from 10 to 100 nm s...

A novel colloidal approach toward semiconductor/metal nanocomposites is presented. Organic-soluble anatase TiO(2) nanorods are used for the first time to stabilize Ag nanoparticles in optically clear nonpolar solutions in the absence of specific ligands for silver. Metallic silver is generated upon UV illumination of deaerated TiO(2) solutions containing AgNO(3). The Ag nanoparticles can be obt...

Lowering the overpotential for the electrochemical conversion of CO2 to useful products is one of the grand challenges in the Department Of Energy report, “Catalysis for Energy”. In a previous paper, we showed that CO2 conversion occurs at low overpotential on a 1-ethyl-3methylimidazolium tetrafluoroborate (EMIM-BF4)-coated silver catalyst in an aqueous solution of EMIM-BF4. One of the surprise...

Abstract Ranging from silver‐entrapped dyes and gold‐entrapped enzymes through palladium‐entrapped graphene oxide, molecularly doped metals (or metal organic alloys, MORALs) are active, stable uniquely versatile catalysts in a number of reactions relevance to the chemical industry. Reactions successfully catalyzed by MORALs concern both industry's main sectors, producing bulk fine chemicals. Th...
