Carbon Supported Oxide-Rich Pd-Cu Bimetallic Electrocatalysts for Ethanol Electrooxidation in Alkaline Media Enhanced by Cu/CuOx
Different proportions of oxide-rich PdCu/C nanoparticle catalysts were prepared by the NaBH4 reduction method, and their compositions were tuned by the molar ratios of the metal precursors. Among them, oxide-rich Pd0.9Cu0.1/C (Pd:Cu = 9:1, metal atomic ratio) exhibits the highest electrocatalytic activity for ethanol oxidation reaction (EOR) in alkaline media. X-ray photoelectron spectroscopy (...
متن کاملBimetallic nanowires as electrocatalysts for nonenzymatic real-time impedancimetric detection of glucose.
Gold-platinum nanowires are proposed as electrocatalysts for a real-time nonenzymatic impedancimetric detection of glucose. The electrochemical behavior of the obtained platform toward electrocatalytic oxidation of glucose, including a proposal for the detection mechanism, is shown.
متن کاملGold-silver bimetallic porous nanowires for surface-enhanced Raman scattering.
Highly porous bimetallic nanowires manufactured via a simple galvanic reaction have demonstrated superior activity in surface-enhanced Raman scattering, allowing ultrasensitive chemical detections on isolated porous nanowires in comparison to pristine silver nanowires.
متن کاملNi@Pt core-shell nanoparticles as an improved electrocatalyst for ethanol electrooxidation in alkaline media
Core-shell nanostructures are emerging as more important materials than alloy nanostructures and have much more interesting potential applications in various fields. In this work, we demonstrated the fast and facile synthesis of core-shell nanoparticles consisting of Pt thin layer as the shell and Ni nanoparticles as the cores. The described method herein is suitable for large-scale and low-cos...
متن کاملEnhanced Electrocatalytic Activity of Pt-M (M= Co, Fe) Chitosan Supported Catalysts for Ethanol Electrooxidation in Fuel Cells
Here, metal nanoparticles were synthesized by chemical reduction of the corresponding metal salts in the presence of chitosan polymer. Binary and ternary metallic-chitosan Pt-Fe-CH, Pt-Co-CH and Pt-Fe-Co-CH nanocomposites were prepared. Transmission electron microscopy images and UV–Vis spectra of the nanocomposites confirmed the presence of the metal nanoparticles. The electrocatalytic activit...
