Co 3 O 4 nanocrystal ink printed on carbon fiber paper as a large-area electrode for electrochemical water splitting

A large-area, self-supported Co3O4 nanocrystal/carbon fiber electrode for oxygen and hydrogen evolution reaction was fabricated via thermal decomposition of the [Co(NH3)n](2+)-oleic acid complex and subsequent spray deposition. Due to the exposed active sites and good electrical conductivity, its…
