摘要

目前，制约可充电锌空气电池产业化的关键因素之一是其耐久性的不可靠性。这项研究通过成功地创造一种可靠的双功能电催化剂来解决这个问题。通过构建碳纳米管（CNTs），钴原子被封装在其中（Co@CNT）。通过将CeO2与Co@CNT结合，在CNTs表面涂覆CeO2涂层，CNTs的结构坚固且具有良好的耐腐蚀性（Co@CNT@CeO2）。这种选择可以防止碳纳米管中活性物质的损失，同时支持与外部环境的平稳传质。CeO2在这些电催化剂中的相容性和保护特性显著提高了稳定性，使其有望成为长周期ZABs。

Improved stability of oxygen evolution reaction and oxygen reduction reaction by CeO2 coating for zinc-air batteries

Currently, one of the key constraints to the industrialization of rechargeable Zinc-Air Batteries (ZABs) is the unreliability of their durability. This study tackles the issue by successfully creating a reliable bifunctional electrocatalyst. By constructing carbon nanotubes (CNTs), cobalt atoms are encapsulated within them (Co@CNT). By combining CeO₂ with Co@CNT,applying a CeO₂ coating on CNTs establishes a sturdy structure with good corrosion resistance (Co@CNT@CeO₂). This choice prevents the loss of active substances in CNTs while supporting smooth mass transfer with the external environment. The compatibility and protective features of CeO₂ in these electrocatalysts significantly improve stability, making them promising for long-cycle ZABs.
