Abstract

Indirect electrocatalitical oxidation of various aliphatic alcohols (butanol-1, nonanol-1, and decanol-1) on the nickel oxide hydroxide electrode by in situ-electrogenerated active oxygen species has been investigated. The research studies the influence of the operative parameters (such as a current density, a quantity of passed electricity and the active oxygen forms generation schemes) on the oxidation process efficiency. It has been shown that using the paired electrolysis scheme significantly increases the efficiency of alcohol oxidation process to corresponding carboxylic acid. The current efficiency of target products is follows: butyric acid 167.5 %, pelargonic acid – 83.8 % and cupric acid – 63.6 %. These results are significantly higher than using oxidation scheme without active oxygen spesies generation
