Cobalt-Induced Magnéli Phase Transformation Towards Oxygen Evolution and Oxygen Reduction Reactions

Hydrothermal deposition of cobalt on mixed-phase titanium suboxides, Ti5O9 and Ti8O15 (TSO), was performed under mild conditions. High-temperature treatment under a reducing atmosphere led to a phase reversal, contrary to the expected Co-doping into the TSO. Surface cobalt specie...
