A mesoporous Fe/N/C ORR catalyst for polymer electrolyte membrane fuel cells: 点击次数：; 发表刊物：Chinese Journal of Catalysis; 关键字：Fe/N/C catalystNon-platinum catalystOxygen reduction reactionMesoporeHollow-shell structure; 摘要：Fe/N/C is a promising non-platinum catalyst for the oxygen reduction reaction (ORR). Even so, mass transfer remains a challenge in the application of Fe/N/C to proton exchange membrane fuel cells, due to the high catalyst loadings required. In the present work, mesoporous Fe/N/C was synthesized through heat treatment of KJ600 carbon black coated with poly-2-aminobenzimidazole and FeCl3. The as-prepared Fe/N/C possesses a unique hollow-shell structure that contains a buffer zone allowing both water formation and vaporization, and also facilitates the mass transfer of gaseous oxygen. This catalyst generated an oxygen reduction reaction activity of 9.21 A/g in conjunction with a peak power density of 0.71 W/cm2.; 论文类型：期刊论文; 学科门类：工学; 文献类型：J; 期号：37; 页面范围：1103-1108; 是否译文：否; 发表时间：2016-07-05; DOI码：10.1016/S1872-2067(16)62471-3; 第一作者：Wei Shi; 合写作者：Shi-Gang Sun,Chi Chen,Yu-Cheng Wang; 通讯作者：Zhi-You Zhou,Xiao-Dong Yang; 发布期刊链接：https://doi.org/10.1016/S1872-2067(16)62471-3
