以酸性溶液中的硫化铁为原料，在多孔活性炭中吸附溶液，然后在氨水中进行热处理，制备了非贵金属催化剂(NNMC)。在600 mV下进行了旋转环盘电极(RRDE)测量和24小时恒电位测量。结果表明，这些催化剂对氧还原具有很高的活性，且具有良好的稳定性。该催化剂的活性和稳定性与文献报道的最好的非贵金属催化剂相当。(C)2011年成立的电化学学会。[DOI：10.1149/2.023202jes]版权所有。
Non-noble metal catalysts (NNMC) have been prepared from iron sulfide in acidic solution by imbibing the solution into a porous activated carbon, followed by heat treatment in ammonia. Rotating ring disk electrode (RRDE) measurements have been performed along with 24 hour potentiostatic measurements at 600 mV. These catalysts were found to be very active for oxygen reduction and had good stability over time. The activity and stability are comparable to the best non-noble metal catalysts reported in the literature. (C) 2011 The Electrochemical Society. [DOI: 10.1149/2.023202jes] All rights reserved.
