Abstract
The impact of TaOx interlayers prepared by thermal decomposition using different solvents (ethanol, n-butanol, ethylene glycol) on Ti/TaOx/IrO2-Ta2O5 electrodes has been investigated using analytical methods such as SEM, XRD, XPS, FIB-TEM, and electrochemical techniques. The results demonstrate that the synthesized TaOx interlayers are mainly composed of amorphous TaOx and a little of Ta2O5 crystallites with a thin TiOx sublayer on titanium substrate. The solvents affect the TaOx loadings and fractions of surface cracks due to the difference in viscosity. The Ti/TaOx/IrO2-Ta2O5 electrode with the interlayer prepared using ethylene glycol has the largest electrochemically active surface area and electrocatalytic activity for oxygen evolution reaction, while the electrode with the TaOx interlayer formed using n-butanol as solvent presents highest stability.
期刊介绍：
Electrocatalysis is cross-disciplinary in nature, and attracts the interest of chemists, physicists, biochemists, surface and materials scientists, and engineers. Electrocatalysis provides the unique international forum solely dedicated to the exchange of novel ideas in electrocatalysis for academic, government, and industrial researchers. Quick publication of new results, concepts, and inventions made involving Electrocatalysis stimulates scientific discoveries and breakthroughs, promotes the scientific and engineering concepts that are critical to the development of novel electrochemical technologies.
Electrocatalysis publishes original submissions in the form of letters, research papers, review articles, book reviews, and educational papers. Letters are preliminary reports that communicate new and important findings. Regular research papers are complete reports of new results, and their analysis and discussion. Review articles critically and constructively examine development in areas of electrocatalysis that are of broad interest and importance. Educational papers discuss important concepts whose understanding is vital to advances in theoretical and experimental aspects of electrochemical reactions.
