Abstract
LiNi0.8Al0.2O2 with a higher Ni3+/Li+ ordering, synthesized by the solution‐combustion method, gives oxygen‐evolution‐reaction (OER) activity in alkaline solution that is comparable to that of IrO2. This confirms that the octahedral‐site NiIV/NiIII couple in an oxide is an active redox center for the OER with redox energy pinned at the top of the O‐2p bands.Keywords
