Summary: Oxygen vacancies (Ov) engineering has been shown to greatly enhance electrocatalytic kinetics for oxygen evolution reaction (OER) by improving electronic transport. However, the mechanism behind this enhancement is not well understood. In this study, we investigate the role of superficial Ov in enhancing the catalytic potential of NiFe layered double hydroxides for OER. We find that superficial Ov engineering significantly reduces the charge transport resistances and modulates the utilization rate of active sites for OER catalysis.

Summary: F-doped layered double perovskites exhibit bifunctional activity in both solid oxide fuel cell and solid oxide electrolysis cell models, attributed to increased oxygen vacancy concentration and enhanced electrical conductivity induced by F doping. The F- anions are successfully introduced into the host lattice, promoting the oxygen surface exchange/diffusion rates. The covalence between Co 3d and O 2p-orbital is enlarged in the F-doped model, leading to improved oxygen reduction and oxygen evolution reaction activities.

Summary: The authors find that Ir-doped calcium copper titanate (CCTO) perovskite exhibits ultrahigh mass activity for the acidic oxygen evolution reaction (OER). By substituting Ti with Ir, the metal-oxygen covalency is significantly increased, leading to a reduced energy barrier for charge transfer. CCTO, as a highly polarizable perovskite, possesses low defect formation energy for oxygen vacancy, inducing a high number of oxygen vacancies in Ir-doped CCTO (Ir-CCTO). Electron transfer occurs from the oxygen vacancies and Ti to the substituted Ir, resulting in favorable adsorptions of oxygen intermediates at Ti sites and efficient charge supplies during OER.
