Direct and Indirect Methods of Electrosynthesis of Hydrogen Based on Hydrogen Sulfide
An effective method for hydrogen electrosynthesis has been proposed, based on direct/indirect oxidation of H2S into sulfur, accompanied by a release of H2 in the cathodic reaction in an organic medium at room temperature. Direct oxidative activation of H2S has been studied by varying the controlled parameter (potential or current), the nature of the solvent and background electrolyte, the electrode material, and the reaction duration. An alternative approach to converting H2S into hydrogen and sulfur has been implemented using mediators of various structures. The most appropriate approach has turned out to be the use of 1,4-diazabicyclo[2.2.2.]octane as a mediator of H2S oxidation in N-methyl-2-pyrrolidone, with a decrease in the electrolysis potential by 0.8 V compared to the direct anodic process.
期刊介绍：
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
