摘要

We systematically studied the catalytic activity of the oxygen evolution reaction (OER) for the tetragonal spinel oxide Mn3-xCoxO4 (0 <= x < 1 and 1 < x <= 1.5). The OER catalytic activity of Mn3-xCoxO4 (0 <= x < 1) dramatically improved with an increase in Co content. We found that the OER activity of Mn3-xCoxO4 (0 <= x < 1) increased linearly with the suppression of the Jahn-Teller distortion. We therefore propose that the Jahn-Teller distortion plays an important role in the OER activities of compounds containing Mn3+. Mn3-xCoxO4 (0 <= x < 1) provides a rare case for directly studying the effect of the Jahn-Teller distortion on OER activity.
