报道了一种在氦气中通过热处理聚（3，5-吡啶）与炭黑的混合物来合成无金属氧还原催化剂的直接方法。采用X射线衍射、光电子能谱、循环伏安和旋转圆盘电极等方法对催化剂进行了表征。该催化剂在碱性介质中表现出与铂基催化剂相当的催化活性。(C)2011 Elsevier B. V.保留所有权利。
A straight-forward method for the synthesis of metal-free catalysts for oxygen reduction by thermal treatment of a mixture of poly(3,5-pyridine) with carbon black in helium is reported. The catalyst was characterized by X-ray diffraction and photoelectron spectroscopy, cyclic voltammetry and rotating disk electrode measurements. The new catalyst exhibited remarkable activity similar to Pt-based catalysts in alkaline media. (C) 2011 Elsevier B.V. All rights reserved.
