Nanowires composed of noble metals are attractive candidates for chemical sensors because they are both ductile and chemically stable in air. The single application where electrodeposited metal nanowires have had the largest impact is that of hydrogen gas (H2) sensing. The development of sensitive, selective, power-effi cient, rapid-responding, and inexpensive H2 sensors, for the purpose of det...

Palladium nanoparticles are of great interest in many industrial fields, ranging from catalysis and hydrogen technology to microelectronics, thanks to their unique physical and chemical properties. In this work, palladium clusters have been prepared by reduction of [PdCl4](2-) ions with ethylene glycol, in the presence of poly(N-vinyl-2-pyrrolidone) (PVP) as stabilizer. The stabilizer performs ...

Abstract Herein, we demonstrate the effectiveness of surface-enhanced Raman scattering (SERS) to detect trace concentration potentially harmful imidacloprid pesticide. To achieve this ultimate objective, a rapid and highly effective methodology for fabrication active stable porous silicon (PSi) plated palladium nanoparticles (PdNPs) SERS substrates by an electrochemical anodization immersion pl...

Multi-metallic alloy nanoparticles (NPs) can offer additional opportunities for modifying the electronic, optical and catalytic properties by the control of composition, configuration and size of individual nanostructures that are consisted of more than single element. In this paper, the fabrication of bimetallic Pd-Ag NPs is systematically demonstrated via the solid state dewetting of bilayer ...

Titanium carbide (Ti3C2Tx) MXene possesses various unique physicochemical and catalytic properties. However, the electrochemical CO oxidation performance is not yet addressed experimentally. Herein, Ti3C2Tx (TX=OH, O, F) ordered exfoliated two-dimensional nanosheets ornamented with semi-spherical palladium nanoparticles (2.5 Wt. %) an average diameter of (10±1 nm) (denoted as Pd/Ti3C2Tx) ration...

The photoelectrochemical (PEC) water splitting performance of BiVO4 is partially hindered by insufficient photoresponse in the spectral region with energy below the band gap. Here, we demonstrate that the PEC water splitting efficiency of BiVO4 electrodes can be effectively enhanced by decorating Pd nanoparticles (NPs) and nanorods (NRs). The results indicate that the Pd NPs and NRs with differ...

Pd(0) nanoparticles with approximately 2 nm diameter, immobilized in 1-n-butyl-3-methylimidazolium hexafluorophosphate ionic liquid, are efficient catalyst precursors for coupling of aryl halides with n-butylacrylate. In situ TEM analysis of the ionic liquid catalytic solution after the catalytic reaction shows the formation of larger nanoparticles ( approximately 6 nm). The palladium content i...

Abstract Among biogenic methods employed for synthesizing various nanoparticles (NPs), gum tragacanth (TGC)-mediated NP production is important. The TGC not only qualifies the principles of green chemistry but also embraces unique qualities. In this perspective, current review concentrates on composition, uses, and exploitation towards metal silver (Ag), gold (Au), palladium (Pd), platinum (Pt)...

Viral templates are highly versatile biotemplates used for the synthesis of nanostructured materials. Rotavirus VP6 self-assembles into nanotubular hollow structures with well-defined diameters and variable lengths, serving as a nucleic acid-free biotemplate to synthesize metal nanoparticles of controlled size, shape, and orientation. Molecular docking simulations show that exposed residues (H1...
