中文摘要: |
开发高效、廉价的碳基氧还原(ORR)催化剂是质子交换膜燃料电池等先进能源系统商业化应用的关键。以金属有机框架材料 ZIF-67为原料,通过热处理、磷掺杂等过程得到高性能的ORR催化剂。该催化剂对ORR具有优异的催化性能,相较于商业Pt/C催化剂,其具有更高中部电位(Half-wave potential)。与此同时,该催化剂还具有非常好的甲醇耐受性与稳定性,并对四电子催化过程具有非常高的选择性。 |
英文摘要: |
Development of highly active carbon-based ORR catalyst is key to the commercialization of advanced energy systems like proton exchange membrane fuel cells. In this work, a P-doped carbon catalyst was fabricated by using ZIF-67 as the precursor and the catalyst exhibited high ORR performance. Compared with commercial Pt/C catalyst, the catalyst showed more positive half-wave potentials. Moreover, the catalyst also demonstrated excellent methanol tolerance and sta⁃bility, as well as a rather high selectivity towards four-electron path during the ORR procedure. |
