Assembly of trimetallic palladium-silver-copper nanosheets for efficient C2 alcohol electrooxidation

نویسندگان

چکیده

The synthesis of two-dimensional (2D) alloyed efficient electrocatalysts with several active sites has attracted considerable attention in recent years. In this work, trimetallic palladium-silver-copper (PdAgCu) nanosheet assemblies (NSAs) are synthesized the presence cetyltrimethylammonium bromide and molybdenum hexacarbonyl as structure-directing agents. morphologies structures PdAgCu NSAs identified by high-angle annular dark-field scanning transmission electron microscopy, X-ray diffraction. Pd6Ag3Cu2 NSA high electrocatalytic performance outstanding long-term stabilities for ethylene glycol oxidation reaction (EGOR = 5696 mA mgPd−1) ethanol (EOR 4374 mgPd−1). enhanced activities can be attributed to synergistic effects, including strain, ligand, bifunctional effects. Furthermore, mechanisms toward C2 alcohols determined, concentrations OH− favor EGOR EOR.

Palladium thorn clusters as catalysts for electrooxidation of formic acid

Pure palladium thorn clusters were synthesized using the electrodeposition method. The clusters were composed of several thorns growing on one basis. Each thorn was composed of hexahedral units with decreasing sizes. The whole thorn was a single crystal along the <220> direction. The cluster was synthesized by square wave electrodeposition. By changing the deposition factors, a mixture of thorn...

Evaluation of thiouracil-based adhesive systems for bonding cast silver-palladium-copper-gold alloy.

This study aimed to evaluate the effect of adhesive systems based on a thiouracil monomer on bonding to silver-palladium-copper-gold (Ag-Pd-Cu-Au) alloy (Castwell M.C.12). Disk specimens were cast from the alloy and then air-abraded with alumina. The disks were bonded using six bonding systems selected from four primers and three luting materials. Shear bond strengths were determined both befor...

Functionalized ultrathin palladium nanosheets as patches for HepG2 cancer cells.

Flexible, charged Pd nanosheets were prepared by using short chain thiolated carboxylic acids and amines. They could wrap around amine or hydroxyl functionalized micron-sized spheres driven by electrostatic interactions. Upon incubation with HepG2 cells, the positively charged cysteamine (CA) functionalized Pd nanosheets exhibited a much higher cytotoxicity, showing more than 80% cell death at ...

Monodispersed platinum nanocubes for enhanced electrocatalytic properties in alcohol electrooxidation.

We report Pt nanocubes of ∼4.5 nm in size synthesized by thermal decomposition in the presence of PVP. The Pt cubic electrocatalysts with dominantly exposed {100} facets show much improved electrocatalytic activities in methanol, ethanol and formic acid electrooxidation.
