Abstract

By taking inspiration from the catalytic properties of single-site catalysts and the enhancement of performance through ionic liquids on metal catalysts, we exploited a scalable way to place single cobalt ions on a carbon-nanotube surface bridged by polymerized ionic liquid. Single dispersed cobalt ions coordinated by ionic liquid are used as heterogeneous catalysts for the oxygen evolution reaction (OER). Performance data reveals high activity and stable operation without chemical instability.

摘要

受单原子催化剂的催化特性以及离子液体对金属催化剂性能提升的启发，我们开发了一种可扩展的方法，将单个钴离子置于由聚合离子液体桥接的碳纳米管表面上。由离子液体配位的单分散钴离子可用作析氧反应 (OER) 的多相催化剂。性能数据显示，该催化剂具有高活性和稳定的操作，且不存在化学不稳定性。
