Lattice Strain Mediated Reversible Reconstruction in CoMoO·0.69HO for Intermittent Oxygen Evolution.

A heterogeneous interface usually plays a versatile role in modulating catalysis and the durability of hybrid electrocatalysts for oxygen evolution reaction (OER), and its intrinsic mechanism is still in dispute due to an uncertain correlation of initial, intermediate and active phases. In this article, the CoMoO·0.69HO/CoO heterogeneous interface is configured to understand the evolution kinetics of these correlated phases.
