evolution reaction (OER). [9][10][11][12][13][14][15][16][17][18][19] Beyond these reactions, the potential application of transition metal oxides for other energy related process is limited.The hydrogen evolution reaction (HER) is a key process in clean hydrogen fuel production. [20,21] To date, theoretical and experimental work on development of new electrocatalysts for HER has largely focused on metallic materials. [22][23][24] Transition metal oxides are generally regarded as catalytically inert for HER because of inappropriate hydrogen adsorption energies. [25,26] Markovic and co-workers [20] suggested a metal/metal-oxide interface to enable hydrogen adsorption on adjacent metal sites to enhance overall HER. This pioneer work stimulates the synthesis of nanostructured metal/ metal-oxide hybrid catalysts to maximize heterojunctions, thus enhance the HER performance. [24,[26][27][28] Recently, we have shown that exerting lattice strain on the surface region of pure oxide can fine-tune the hydrogen adsorption energy toward the optimum region. This resulted in an intrinsic activity close to the top of a volcano plot for alkaline HER catalysts. [29] Despite these advances, the apparent activity of transition metal oxides for HER is significantly less than that of the present state-of-the-art Pt/C catalyst. This mainly arises from the intrinsic, low electronic conductivity of transition metalThe ORCID identification number(s) for the author(s) of this article can be found under https://doi.

air batteries (ZABs) have recently received tremendous research attention due to their high theoretical energy densities. However, current ZABs suffer from poor energy efficiency and cyclability, mainly owing to the sluggish kinetics of the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) on the air electrode. Therefore, rational design of efficient bifunctional oxygen electrocatalysts with high activity and stability is essential for improving battery performance. Carbon-based nanomaterials are promising candidates for bifunctional oxygen catalysis. In this review, we present the latest development of carbon-based bifunctional electrocatalysts for ZABs. Firstly, the related reaction mechanisms of bifunctional ORR/OER catalysts are introduced. Then, the recent advances in developing carbon-based bifunctional catalysts with tailored structure and promising catalytic performance are introduced following the regulation strategies, e. g., heteroatom doping, defect engineering, and/or hybridizing with other active materials. Finally, the key challenges and perspectives of advanced ZABs are provided to better shed light on future research. . This review aims to provide timely information of the carbon-based bifunctional oxygen catalysts for researchers and to shed light on the future development of high-performance catalysts and ZABs. 2 3 4 5 6 7 8
