The hydrogen rising economy is demanding an active and durable electrocatalysts
based on low-cost, earth abundant materials for water electrolysis.
Oxygen electrochemistry plays a key role in renewable energy technologies, but the
slow kinetics of oxygen evolution reaction limit the performance and
commercialization such as devices.
Nonetheless, most of the previous work has been focus on precious metals and
there are no guidelines for the choice of oxides as evolving oxygen electrodes.
Up to now, iridium dioxide and ruthenium dioxide are the state-of-the-art oxygen
evolution reaction electrocatalysts with low overpotential and Tafel slope.
In this work, has been focused on the combination of an electrically conductive
titanium powder matrix, titanium oxide because the strong oxidizing power of its
holes, high photostability and redox selectivity and nickel due to its excellent
performance and stability for the evolution of oxygen. In addition, the study of the
role of metal/metal oxide couple required for the evolution of oxygen. [-]
