%X 锌空气电池具有能量密度高、成本低等优点&#65292;是最具前途的绿色储能技术之一&#65292;开发用于空气阴极氧还原反应(ORR)和析氧反应(OER)的非贵金属催化剂至关重要。本文提出了一种新型高效的制备方法&#65292;通过热处理与电沉积技术&#65292;以不锈钢网为基底原位生长NiO包裹的氮掺杂碳纳米管三维网络(NiO-CNT/SS)。得益于碳纳米管的独特三维结构&#65292;使其可以暴露出更多的活性位点&#65292;所制备催化剂OER性能优良&#65292;在100 mA cm<sup>&#8722;</sup><sup>2</sup>电流密度下过电位仅为374 mV。此外&#65292;NiO-CNT/SS材料所组装的锌空气电池具有1.44 V开路电压以及优异的循环稳定性&#65292;在5 mA cm<sup>&#8722;</sup><sup>2</sup>电流密度下可以稳定循环145 h而无明显衰减。<br>Zn-air battery has been regarded as one of the most promising green energy storage technologies due to its high energy density and low cost. It is very important to develop non-noble metal catalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). In this paper, a new and efficient preparation method is proposed to develop three-dimensional network of nitrogen-doped carbon nanotubes wrapped by NiO (NiO-CNT/SS) in-situ grown on stainless steel mesh by heat treatment and electrodeposition technology. Benefiting from the unique three-dimensional structure of carbon nanotubes, it can expose more active sites, and the prepared catalyst has excellent OER performance, with an overpotential of only 374 mV at a current density of 100 mA cm<sup>&#8722;</sup><sup>2</sup>. In addition, the zinc-air battery assembled with NiO-CNT/SS material has an open circuit voltage of 1.44 V and excellent cycle stability. It can cycle stably for 145 h without significant attenuation at a current density of 5 mA cm<sup>&#8722;</sup><sup>2</sup>.
