“…165 Co-based materials are also another important type of cathode catalysts. 132,166,167 The hybrid of Co 3 O 4 and graphene This journal is © The Royal Society of Chemistry 2023 oxide (GO) exhibited surprisingly high activity for the ORR, even far exceeding Pt/C catalysts, even though these two ingredients showed minimal catalytic activity individually. The improvement in ORR efficiency might be ascribed to the optimization of the formation of the electronic structure, stemming from the formation of Co-O bonds on graphene.…”

“…Figure 7(e) shows the schematic representation of ZABs and discharge polarization, along with a power density curve for ZABs that have been equipped with designed electrocatalysts. Qin et al [138] designed a novel electrocatalyst consisting of CoO and CoS 2 for ZABs to effectively overcome issues related to sluggishness and conduction capacitance. The electrochemical behaviour of CoO/CoS2 as an electrocatalyst is influenced by its defective nature and the electronic configuration variation of multiple elements in the heterojunctions of the interface.…”

In recent years, the rapid growth in renewable energy applications has created a significant demand for efficient energy storage solutions on a large scale. Among the various options, rechargeable zinc‐air batteries (ZABs) have emerged as an appealing choice in green energy storage technology due to their higher energy density, sustainability, and cost‐effectiveness. Regarding this fact, a spotlight is shaded on air electrode for constructing high‐performance ZABs. Cobalt oxide‐based electrocatalysts on the air electrode have gained significant attention due to their extraordinary features. Particularly, exploration and integration of bifunctional behavior for energy storage has remarkably promoted both ORR and OER to facilitate the overall performance of the battery. The plot of this review is forwarded towards in‐depth analysis of the latest advancements in electrocatalysts that are based on cobalt oxide and possess bifunctional properties along with an introduction of the fundamental aspects of ZABs, Additionally, the topic entails an examination of the morphological variations and mechanistic details mentioning about the synthesis processes. Finally, a direction is provided for future research endeavors through addressing the challenges and prospects in the advancement of next‐generation bifunctional electrocatalysts to empower high‐performing ZABs with bifunctional cobalt oxide.

Due to the energy crisis by the excessive consumption of fossil fuels, Zinc–air batteries (ZABs) with high theoretical energy density have attracted people‘s attention. The overall performance of ZABs is largely determined by the air cathode catalyst. Therefore, it is necessary to develop high‐efficiency and low‐cost bifunctional catalysts to replace noble metal catalysts to promote the development of ZABs. Among a variety of cathode catalysts, TMS has become a research hotspot in recent years because of its better electrical conductivity than metal phosphides and metal oxides. In this work, we focus on the means of improving the electrocatalytic performance of transition‐metal sulfides (TMS) providing ideas for us to rationally design high‐performance catalysts. Furthermore, the performance improvement law between catalyst performance and ZABs is also discussed in this work. Finally, some challenges and opportunities faced in the research of TMS electrocatalysis are briefly proposed, and strategies for improving the performance of ZABs are prospected.
