Problems solved by technology

[0003] However, to reduce these compounds with low affinity to water and low conductivity by electrochemical reaction using water as raw material, it is obviously necessary to work hard on the electrode structure and electrode materials. The reduction reaction of compounds requires the development of electrode catalysts suitable for this purpose

Abstract

An electrolysis cell has an electrolyte membrane, a reduction electrode, and an oxygen evolving electrode. The electrolyte membrane is formed of a material having protonic conductivity (ionomer). A reduction catalyst used for the reduction electrode is composed of a composition containing a first catalyst metal (noble metal) that contains at least one of Pt and Pd and containing one or more kinds of second catalyst metals selected from among Cr, Mn, Fe, Co, Ni, Cu, Zn, Mo, Ru, Sn, W, Re, Pb, and Bi. The oxygen evolving electrode contains catalysts of noble metal oxides such as RuO2, IrO2, and the like.

Description

technical field [0001] The present invention relates to a device and a method for electrochemically hydrogenating aromatic hydrocarbon compounds or nitrogen-containing heterocyclic aromatic compounds. Background technique [0002] It is known that cyclic organic compounds such as cyclohexane and decahydronaphthalene can be efficiently obtained by nucleohydrogenating corresponding aromatic hydrocarbon compounds (benzene, naphthalene) with hydrogen. This reaction requires high-temperature and high-pressure reaction conditions, and therefore, production on a small to medium scale is not suitable. On the other hand, it is known that the electrochemical reaction using an electrolytic cell can use water as a hydrogen source, so there is no need to handle gaseous hydrogen, and the reaction conditions are relatively mild (normal temperature to about 200°C, normal pressure). [0003] However, to reduce these compounds with low affinity to water and low conductivity by electrochemica...
