Electrocatalytic Activity of Palladium Nanocatalysts Supported on Carbon Nanoparticles in Formic Acid Oxidation
Palladium nanostructures were deposited onto carbon nanoparticle surface by a chemical reduction method. Transmission electron microscopic studies showed that whereas the resulting metal-carbon (Pd-CNP) nanocomposites exhibited a diameter of 20 to 30 nm, the metal components actually showed a cauliflower-like surface morphology that consisted of numerous smaller Pd nanoparticles (3 to 8 nm). El...
متن کاملEnzymic oxidation of formic acid.
Interest in the metabolic fate of formic acid has been renewed as the result of recent experiments showing active incorporation of carbon-labeled formate into normal body constituents of the pigeon (l-3) and the rat (4, 5). Prior to these findings, enzymes capable of catalyzing the oxidation of formic acid had been reported, widely distributed in plant and animal tissues (6). Only in the case o...
متن کاملNanocatalysts Impregnated Polythiophene Electrodes for the Electrooxidation of Formic Acid
Conductive and porous polythiophene (PTh) films, which are used as host matrices for Pt and Pt/Pd nanoparticles, are synthesized electrochemically. PTh films containing nanometre-sized Pt and Pt/Pd bimetallic particles are electro synthesized on an indium tin oxide (ITO) glass plate by voltammetric cycling between –0.1 to +1V (Vs Ag/AgCl / 2M NaCl). The ensuing PTh electrode, modified with nano...
متن کاملElectrocatalytic activity of Pd-Co bimetallic mixtures for formic acid oxidation studied by scanning electrochemical microscopy.
The electrochemical oxidation of formic acid was studied by the tip generation-substrate collection (TG-SC) mode of scanning electrochemical microscopy (SECM), extending the number of applications of SECM in electrocatalysis. Formic acid was generated at a Hg on Au ultramicroelectrode (UME) tip by reduction of CO(2) in a 0.1 M KHCO(3) solution saturated with this gas. The electrocatalytic activ...
متن کاملIridium-platinum alloy nanoparticles: Composition-dependent electrocatalytic activity for formic acid oxidation†
IrxPt100 x alloy nanoparticles with varied compositions (x1⁄4 100, 75, 67, 50, 34, and 0) were synthesized by a thermolytic process at varied ratios of the IrCl3 and PtCl2 precursors. High-resolution transmission electron microscopic (HRTEM) measurements showed that the nanoparticles all exhibited well-defined crystalline structures with the average core diameters around 2 nm; and the elemental...
