However, the sluggish kinetics of the oxygen reduction reaction (ORR) at the cathode significantly limits their practical applications. In this study, we successfully fabricated MnO₂ nanotube arrays (MnO₂-NTA) grown in situ on a carbon cloth (CC) substrate using a hydrochloric acid-assisted hydrothermal method. The resulting MnO₂-NTA@CC electrode demonstrated excellent electrocatalytic performance and stability for ORR, with an initial potential of approximately − 0.15 V and a half-wave potential around − 0.3 V. Furthermore, the electrode exhibited a diffusion-limited current density of 5.0 mA/cm² at a rotation speed of 2000 rpm and maintained a loss of less than 0.015 V in the half-wave potentials after 10000 CV cycles, indicating outstanding durability. Theoretical calculations revealed that the MnO₂ (200) surface efficiently catalyzes oxygen reduction via a four-electron pathway, with the *OOH to *O transition being the rate-determining step. This excellent catalytic activity can be attributed to the unique hollow nanotube architecture, providing abundant active sites and enhancing electron and oxygen transport. Additionally, the integrated MnO₂-NTA@CC structure eliminates the need for binders and functions as a gas diffusion layer, simplifying the electrode preparation process and reducing manufacturing costs. When directly employed as the cathode in magnesium-air batteries, the MnO₂-NTA@CC electrode achieved a stable open-circuit voltage of 1.5 V and a peak power density of 14.91 mW/cm². These results demonstrate that the MnO₂-NTA@CC electrode is a promising candidate for high-performance magnesium-air batteries and provide valuable insights into the design of efficient air electrodes for future energy storage systems.</p></div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142518670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
