As a H2O2 generator, a 2e− oxygen reduction reaction active electrocatalyst plays an important role in the advanced oxidation process to degrade organic pollutants in sewage. To enhance the tendency of NiCo2S4 towards the 2e− reduction reaction, N atoms are doped in its structure and replace S2−. The result implies that this weakens the interaction between NiCo2S4 and OOH*, suppresses O−O bond breaking and enhances H2O2 selectivity. This electrocatalyst also shows photothermal effect. Under photothermal heating, H2O2 produced by the oxidation reduction reaction can decompose and releaseOH, which degrades organic pollutants through the advanced oxidation process. Photothermal effect induced by the advance oxidation process shows obvious advantages over the traditional Fenton reaction, such as wide pH adaptation scope and low secondary pollutant due to its Fe2+ free character. With Zn as anode and the electrocatalyst as cathode material, a Zn−O2 battery is assembled. It achieves electricity generation and photothermal effect induced by the advance oxidation process simultaneously.

“…Similar to the Zn/MnO 2 battery, H + ion insertion into Co 3 O 4 results in the formation of the CoO layer after the discharge process 138 . The reversible conversion reaction of Zn‐Co 3 O 4 battery is as follows:

{Co}_{3} O_{4} goodbreak+ H_{2} normalO goodbreak+ 2 e^{-} \leftrightarrow 3 CoO goodbreak+ 2 {OH}^{-} .

Compared with the Zn–Co 3 O 4 battery with a mild electrolyte, the Zn–Co 3 O 4 battery in the alkaline electrolytes shows different electrochemical reactions 191 . The reaction equation of the Zn–Co 3 O 4 battery is as follows:

(}, \begin{array}{l} {Co}_{3} O_{4} goodbreak+ {OH}^{-} goodbreak+ H_{2} normalO \leftrightarrow 3 CoOOH goodbreak+ e^{-} \\ 3 CoOOH goodbreak+ 3 {OH}^{-} \leftrightarrow 3 {CoO}_{2} goodbreak+ 3 H_{2} normalO goodbreak+ 3 e^{-} \end{array}) {Co}_{3} O_{4} goodbreak+ 4 {OH}^{-} \leftrightarrow 3 {CoO}_{2} goodbreak+ 2 H_{2} normalO goodbreak+ 4 e^{-} .

Benefiting from the advantageous features of high safety, abundant reserves, low cost, and high energy density, aqueous Zn‐based rechargeable batteries (AZBs) have received extensive attention as promising candidates for energy storage. To achieve high‐performance AZBs with high reversibility and energy density, great efforts have been devoted to overcoming their drawbacks by focusing on the modification of electrode materials and electrolytes. Based on different cathode materials and aqueous electrolytes, the development of aqueous AZBs with different redox mechanisms are discussed in this review, including insertion/extraction chemistries (e.g., Zn2+, alkali metal ion, H+, NH4+, and so forth) dissolution/deposition reactions (e.g., MnO2/Mn2+), redox couples in flow batteries (e.g., I3−/3I−, Br2/Br−, and so forth), oxygen electrochemistry (e.g., O2/OH−, O2/O22−), and carbon dioxide electrochemistry (e.g., CO2/CO, CO2/HCOOH). In particular, the basic reaction mechanisms, issues with the Zn electrode, aqueous electrolytes, and cathode materials as well as their design strategies are systematically reviewed. Finally, the remaining challenges faced by AZBs are summarized, and perspectives for further investigations are proposed.
