摘要
为实用锌-空气电池(ZAB)开发低成本、高活性的电催化剂意义重大。本文以氯化钠为模板和插层剂,通过热分解 ZIF 前驱体合成了氯氮共掺空心碳多面体催化剂(Cl-NC-1000)。实验结果表明,氯和氮的协同作用调整了相邻碳原子的电子结构,促进了氧还原反应(ORR)中间产物的捕获/释放,从而增强了其内在活性。因此,制备出的 Cl-NC-1000 催化剂具有出色的 ORR 性能,包括催化活性、选择性和稳定性。在 ZAB 中应用时,Cl-NC-1000 催化剂能在 5 mA cm-2 的电压下保持约 0.96 V 的电压差,循环时间超过 300 h,能量效率高达 53%,优于基于 Pt/C 的商用可充电 ZAB。这项研究为设计具有成本效益和高活性的非金属 ORR 催化剂提供了一种有效的策略。
Chlorine–Nitrogen Doped Hollow Polyhedral Carbon-Based Catalysts for High Performance Zinc–Air Batteries
It is significant to exploit low-cost and high-activity electrocatalysts for practical zinc–air batteries (ZABs). Herein, a chlorine-nitrogen codoped hollow carbon polyhedron catalyst (Cl-NC-1000) is synthesized by the thermal decomposition of ZIF precursors with a template and intercalating agent of NaCl. Experimental results demonstrate that the synergistic effect of chlorine and nitrogen adjusts the electronic structure of neighboring carbon atoms, facilitating the capturing/releasing of oxygen reduction reaction (ORR) intermediates, thereby reinforcing the intrinsic activity. As a result, the fabricated Cl-NC-1000 catalyst exhibits an outstanding ORR performance, including catalytic activity, selectivity, and stability. When applied in ZABs, the Cl-NC-1000 catalyst maintains a voltage difference of ca. 0.96 V at 5 mA cm–2 and cycles over 300 h with an energy efficiency of 53%, superior to those of commercial Pt/C-based rechargeable ZABs. This work provides an efficient strategy for designing cost-effective and high-activity nonmetallic ORR catalysts.
