Switchable wetting of oxygen-evolving oxide catalysts
Vasiliki Tileli, Tzu-Hsien Shen
The surface wettability of catalysts is typically controlled via surface treatments that promote catalytic performance. Here we report on potential-regulated hydrophobicity/hydrophilicity at cobalt-based oxide interfaces with an alkaline solution. The swit ...
NATURE PORTFOLIO2021Oxygen evolution reaction catalyzed by first-row transition metal oxides: stability and mechanism
Water splitting offers the opportunity for storing solar energy and, thus, producing carbon-neutral and renewable solar fuels. The process, known as artificial photosynthesis, is limited by the electrocatalytic conversion of water into molecular oxygen. El ...
EPFL2020Stability of metallo-porphyrin networks under oxygen reduction and evolution conditions in alkaline media
Klaus Kern, Jan Gui-Hyon Dreiser, Markus Etzkorn, Claudius Morchutt, Sebastian Stepanow, Benjamin Wurster
Transition metal atoms stabilised by organic ligands or as oxides exhibit promising catalytic activity for the electrocatalytic reduction and evolution of oxygen. Built-up from earth-abundant elements, they offer affordable alternatives to precious-metal b ...
