Physical electrochemistry of ceramic oxides
TL;DR: In this article, a survey of the industrial needs and demands for ceramic oxide electrodes is presented, along with an analysis of the factors responsible for the electrocatalytic activity of oxides, providing a clue to the understanding of a generalized mechanism of electrode reaction which can be established for most anodic and cathodic electrolytic processes.

TL;DR: In this article, a strategy using Fe substitution was proposed to enable the inactive spinel CoAl2O4 to become highly active and superior to the benchmark IrO2. But, it was not shown that the Fe substitution can facilitate surface reconstruction into active Co oxyhydroxides under OER conditions.
