Oxygen evolution reactions (OER) are important reactions for energy conversion. Metal-free carbon-based catalysts potentially contribute to the catalytic materials for OER. However, it has been difficult to understand the intrinsic catalytic activity of carbon materials, due to catalyst decomposition over the course of long-term reactions. Here, we report high oxygen evolution reaction catalytic activity of F-doped carbon in alkaline media. Intrinsic OER activity was evaluated from a combination of measurements using a rotating disk electrode and O₂ sensor. The F-doped carbon catalyst is a highly active catalyst, comparable to state-of-the-art precious-metal-based catalysts such as RuO₂.
析氧反应（OER）是能量转换的重要反应。无金属碳基催化剂可能有助于用于OER的催化材料。然而，由于在长期反应过程中催化剂分解，一直难以了解碳材料的本征催化活性。在此，我们报道了F掺杂碳在碱性介质中的高析氧反应催化活性。通过使用旋转圆盘电极和O₂传感器的测量组合来评估本征OER活性。F掺杂碳催化剂是一种高活性催化剂，可与RuO₂等最先进的贵金属基催化剂相媲美。
