| Popis: | The controlled synthesis of e-Co, CoO, and Co3O4 nanoparticles with the same stabilizers and with nearly identical particle size and shape allows comparisons of the inherent catalytic properties of these materials in the oxygen evolution reaction (OER). The nanoparticle electrodes exhibit relatively low overpotentials and very similar catalytic activities under basic conditions. The latter observation indicates that all three catalysts operate with similar catalytic mechanisms. |
