Analiza mehanizma reakcije razvoja kisika pri elektrolizi vode

Novak, Filip Jakob (author), Gaberšček, Miran (mentor)

Vodik v najbolj čisti obliki lahko pridobimo z elektrolizo vode, kar pa je trenutno energetsko zelo potratno, saj niso na voljo dovolj kvalitetni katalizatorji. Problematična je predvsem reakcija razvoja kisika, ki poteka v več stopnjah. V diplomskem delu bomo podrobno proučili, kateri elementarni površinski procesi določajo hitrost razvoja kisika pri različnih elektrodnih potencialih. Na tej osnovi bomo predlagali več možnih načinov pohitritve te pomembne večstopenjske reakcije

• Title: Analysis of oxygen formation reaction mechanism at the water electrolysis

Abstract

Hydrogen in its purest form can be obtained by water electrolysis, which is currently highly energy-intensive, for the lack of suficciently quality catalysts. Foremostly problematic is the reaction of oxygen formation, which takes place in several steps. In this thesis, it will be studied in detail, which elementary surface processes determine the rate of oxygen formation at different electrode potentials. On this basis, several possible ways of accelerating this important multistep reaction will be proposed.
