Epitaxy of Ge nanowires grown from biotemplated Au nanoparticle catalysts.
Semiconductor nanowires (NWs) are being actively investigated due to their unique functional properties which result from their quasi-one-dimensional structure. However, control over the crystallographic growth direction, diameter, location, and morphology of high-density NWs is essential to achieve the desirable properties and to integrate these NWs into miniaturized devices. This article pres...
متن کاملSynthesis and Charactrization of Au Nanocomposits by Green Capping Agent: Pomegranate juice For Antibacterial Activity
Objective(s): In this work, pomegranate juice was used as a capping agent for self- assembly to form particles-like Au nanostructures in the presence of AuHCl4.3H2O as aurate source. Besides, to investigate the concentration effect of pomegranate juice as the green capping agent on the morphology and particle size of final products several experiments were...
متن کاملBidentate dicarboxylate capping groups and photosensitizers control the size of IrO2 nanoparticle catalysts for water oxidation.
Dicarboxylic acid ligands (malonate, succinate, and butylmalonate) stabilize 2 nm diameter IrO2 particles synthesized by hydrolysis of aqueous IrCl(6)2- solutions. Analogous monodentate (acetate) and tridentate (citrate) carboxylate ligands, as well as phosphonate and diphosphonate ligands, are less effective as stabilizers and lead to different degrees of nanoparticle aggregation, as evidenced...
متن کاملMicrowave synthesis of supported Au and Pd nanoparticle catalysts for CO oxidation.
We report the microwave synthesis and characterization of Au and Pd nanoparticle catalysts supported on CeO2, CuO, and ZnO nanoparticles for CO oxidation. The results indicate that supported Au/CeO2 catalysts exhibit excellent activity for low-temperature CO oxidation. The Pd/CeO2 catalyst shows a uniform dispersion of Pd nanoparticles with a narrow size distribution within the ceria support. A...
متن کاملSynthesis of Mono- and Bimetallic Au-based Nanoparticle Catalysts Utilizing Solid Phase Dendrimer Templates
Introduction The desire to controllably tune catalyst properties has generated increased interest in the controlled preparation of supported nanoparticle catalysts. Particle size, composition, and morphology may have substantial influences on catalytic activity and, more importantly, selectivity. However, few preparative routes exist to prepare supported catalysts of welldefined morphologies. S...
