The activation of HCl by cationic Au in the presence C2H2 is important for construction active sites and acetylene hydrochlorination. Here, we report a strategy activating Au-based supported ionic liquid phase (Au–SILP) technology with [N(CN)2?] anion. This enables to accept electrons from anions Au–[N(CN)2?] complexes rather than pure [Bmim][N(CN)2], leading notable improvement both reaction p...

This study presents synthesis results of catalysts made perovskite-like oxide La2-xSrxCuO4 (x=0.0, 0.5, 1.0) using the citrate method and crystallisation at 800°C. The structure was characterised by X-ray diffraction (XRD). catalyst activity enhanced with gold (Au) platinum (Pt). Au mounted on sol-gel method. perovskite LaMnO3/LaCuO3 evaluated complete oxidation volatile hydrocarbons (HCs) in a...

A series of gold(I) complexes [AuCl(trz)] were synthesized that contain 1,2,3-triazolylidene (trz) ligands with variable wingtip groups. In the presence of AgBF4, these complexes undergo ligand redistribution to yield cationic complexes [Au(trz)2]BF4 in high yields as a result of efficient carbene transfer. Identical reactivity patterns were detected for carbene gold complexes comprised of Ardu...

Gold was considered catalytically inactive until 1987, when Haruta and co-workers found that gold nanoclusters supported by metal oxides showed high activity toward CO oxidation even below room temperature. Since then, there has been intense interest in the use of Au nanoparticles (NPs) to catalyse a variety of reactions, including low temperature oxidation of CO, selective oxidation of alcohol...

Gold doped TiO2 has been successfully synthesized via the photolysis method and is characterized by different techniques. NPs of gold doped TiO2 were utilized for the degradation of methylene blue as a material pigmentation pollutant. The substitution of Au on TiO2 surface was established via XRD, EDX, TEM, and FT-IR techniques. The TEM and SEM results appea...

In the present study, we carried out chemical synthesis and characterization of Fe3O4@PEG-Au as a magnetic nanocomposite in aqueous solution by chemical co-precipitation of Fe3+ and Fe2+ ions and encapsulated by poly (ethylene glycol) (PEG) in order to enhancing hydrophilicity, biocompatibility and immobilizing gold ions in the presence of NaBH4 as a reducing agent. Nanostructures were characte...

A mesostructured cellular foam (MCF) silica was applied to support gold (Au) – platinum (Pt) alloy nanoparticles (NPs) for benzyl alcohol partial oxidation. catalytic synergy on bimetallic (Au)-platinum nanoparticle (NP) catalyst, referring that introducing Au Pt leading a higher performance has been observed. However, the essence of this synergistic effect is still under debate. In work, serie...

Electrochemical water splitting operated under acidic conditions provides a clean approach to generate hydrogen fuels. Currently, the sluggish kinetics of oxygen evolution reaction (OER) at anode is bottleneck limiting splitting. Here, we report that OER activity Ir, one most commonly used catalysts, can be boosted by forming phase boundaries with Au. Mixed Au and Ir catalysts were synthesized ...

We present electronic transport measurements in individual Au-catalyst/Ge-nanowire interfaces demonstrating the presence of a Schottky barrier. Surprisingly, the small-bias conductance density increases with decreasing diameter. Theoretical calculations suggest that this effect arises because electron-hole recombination in the depletion region is the dominant charge transport mechanism, with a ...
