in this research, we reported a novel modified carbon ceramic electrode (cce) using ni/al layered double hydroxide as modifier was fabricated by sol-gel technique. the ni/al layered double hydroxide modified sol gel derived carbon ceramic (ni/al ldh-sgd-cc) electrode was used for electrocatalytic oxidation of acetaldehyde. the oxidation of acetaldehyde happens at the potential where ni (iii) sp...

The reactivity of the electro-oxidation products N-hydroxyphthalimide (NHPI) with an aromatic alcohol, 4-methoxybenzyl alcohol (MBA) in a sulfuric acid-acetonitrile mixed solution was investigated. Phthalimide N-oxyl radical (PINO·), which is produced by one-electron oxidation NHPI, reacted MBA as well aprotic solvent. Further PINO· also but results showed complex-shaped voltamograms.

Size-selected 3 nm gas-phase Au clusters dispersed by cluster beam deposition (CBD) on a conducting fluorine-doped tin oxide template show strong enhancement in mass activity for the methanol electro-oxidation (MEO) reaction compared to previously reported nanostructured gold electrodes. Density functional theory-based modeling corresponding guided experiments attributes this high MEO density o...

Using vo1tammetric technique with a rotating disk electrode, the anodic oxidation of carbazole in aqueous H2S04 ethanol mixtures was shown to proceed under diffusion and electron transfer control conditions. Electro-oxidation involves one electron transfer; electrode passivation occurs due to the formation of a poorly soluble product. By means of the SCF MO LCAO INDO, AMI-UHF and PM3-UHF method...

We propose a method to enhance the fuel cell efficiency with the simultaneous removal of toxic heavy metal ions. Carbon monoxide (CO), an intermediate of methanol oxidation that is primarily responsible for Pt catalyst deactivation, can be used as an in-situ reducing agent for hexavalent chromium (Cr (VI)) with reactivating the CO-poisoned Pt catalyst. Using electro-oxidation measurements, the ...

The electrocatalytic oxidation of formic acid at a gold electrode functionalized with FePt nanoparticles was studied by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) in a mixed solution of 0.1 M HCOOH and 0.1 M HClO4. The FePt bimetallic nanoparticles, with a mean diameter of 3 nm, were prepared by a chemical reduction method. The Au/FePt nanostructured electrode was ...
