Abstract: Cobalt spinel oxides are ac lass of promising transition metal (TM) oxides for catalyzing oxygen evolution reaction (OER). Their catalytic activity depends on the electronic structure.I naspinel oxide lattice,e acho xygen anion is shared amongst its four nearest transition metal cations,ofwhich one is located within the tetrahedral interstices and the remaining three cations are in the octahedral interstices. This work uncovered the influence of oxygen anion charge distribution on the electronic structure of t… Show more

“…in perovskite ABO 3 . Second, the competition for charges on oxygen anions between metals in octahedral and tetrahedral sites encourages covalency between metal cations and oxygen anions [17]. The relative stable chemistry of spinel oxides makes them follow the adsorbate evolved mechanism (AEM) in most cases [18][19][20] and thus difficult to break the scaling relationship for better OER [21].…”

“…[2] Up to now, the generally recognized state-ofthe-art catalysts for OER are IrO 2 and RuO 2 , while relatively high cost and scarce shortage restrict the widespread application. [3] Therefore, it is meaningful and urgent for researchers to develop catalysts with low cost, superior performance, and strong practicability.Recently, the first-row transition-metal (Mn, Fe, Co, Ni, and Cu) based OER catalysts, including hydroxide, [4] oxides, [5] sulfides, [6] and nitrides, [7] have been widely investigated for their cost-effective features and easy regulation of electronic structure. [8] For example, the large interlayer spacing and nanosheet (NS) structure of Co(OH) 2 are conducive to facilitate ion transport and provide large active area, respectively, which is vital to accelerate the OER kinetics in alkaline electrolytes.…”

“…Highly active energy storage/conversion devices are of great interest owing to their important roles in energy and environmental sustainability. [1] Zinc-air batteries (ZABs) with the advantages of high theoretical energy density,l owcost and eco-friendliness are regarded as promising future power devices. [2] However,t he electrochemical performance of current ZABs is severely affected by the lack of effective bifunctional catalysts for sluggish oxygen evolution reaction (OER)/oxygen reduction reaction (ORR) at the air-cathode.…”
