We have synthesized micrometer-sized Ag nanosheets via a facile, one-step, template-free electrochemical deposition in an ultra-dilute silver nitrate aqueous electrolyte. The nanosheet growth was revealed to occur in three stages: (1) formation of polygonal Ag nuclei on a substrate, (2) growth of {112}-faceted nanowire from the nuclei, and (3) anisotropic growth of (111)-planar nanosheets, appr...

We report a facile green approach to the synthesis of silver nanoparticles (Ag NPs) on the surface of graphene oxide nanosheets functionalized with mussel-inspired dopamine (GO-Dopa) without additional reductants or stabilizers at room temperature. The resulting hybrid Ag/GO-Dopa exhibits good dispersity and excellent catalytic activity in the reduction of nitroarenes.

Linked plasmonic nanoparticles made of noble metal materials exhibit significant enhancement of the amplitude of electromagnetic-field and strongly frequency-selective response at visible ranges which are distinct from that of individual nanoparicles. We introduce recent progress in the fabrication processes to achieve linked plasmonic nanostructures with various configurations. It includes the...

We reported on hydrothermally synthesized zinc oxide (ZnO) nanosheets modified by doping with silver (Ag: 1, 2, 3, 4, and 5%) to improve their electrochemical properties for glucose sensing without an enzyme.

Hybridization of distinct materials into a single nanoplatform is relevant to advance material’s properties for functional application such as biosensor platform. We report the synthesis and characterization of nanosheets of graphene oxide decorated with hybrid nanoparticles of silver-ruthenium bipyridine complex (Ag@[Ru(bpy)3] ) core and chitosan shell. Hybrid nanoparticles were first obtained...

Silver nanoparticle-decorated graphene nanocomposites were synthesized by a facile chemical reduction approach with the assistance of supercritical CO2 (ScCO2). The silver nanoparticles with diameters of 2-16 nm are uniformly distributed and firmly anchored on graphene nanosheets. The tribological properties of the as-synthesized nanocomposites as lubricant additives in engine oil were investig...

Two dimensional silver(I) coordination polymer, [Ag(μ5-T4S)]n (1), (T4S- = toluene-4-sulfonate), has been synthesized and characterized by Inductively Coupled Plasma (ICP) and elemental analyses, IR spectroscopy and powder X-ray diffraction. This compound was calcined at 450, 500 and 700 °C in a furnace and static atmosphere of air. The resultin...

A peony-like Ag/Ag0.68V2O5 hybrid assembled from nanosheets with the thickness of 40 nm was synthesized through a one-pot hydrothermal approach from vanadium pentoxide (V2O5), oxalic acid (H2C2O4), and silver nitrate (AgNO3) at 180 °C for 24 h. The hybrid exhibits high performance as both anode and cathode materials for rechargeable lithium batteries. Electrochemical measurements revealed that ...

In a recent report, we have presented the layer-by-layer (LBL) assembly of a biomimetic nanostructured composite from Na(+)-montmorillonite clay nanosheets and poly(diallylmethylammonium chloride) (Tang, Z.; Kotov, N.; Magonov, S.; Ozturk, B. Nat. Mater. 2003, 2, 413). The structure, deformation mechanism, and mechanical properties of the material are very similar to those of natural nacre and ...

A natural polyphenolic compound was used to assemble nanocomposites. Owing its stable bioactive properties, bamboo has earned significant attention in material science. Its high nutrient content and hydrophilicity makes more vulnerable mold attacks shortened shelf lives. To produce efficient, multipurpose, long-life products, a novel technique involving an immersion dry hydrothermal process app...
