对呀,我也是做非铂催化剂,曲线也都没有极限电流,半波电势好像也蛮多人用。那8楼朋友是怎么确定半波电势的呀?小弟看到Electrochemistry Communications 12 (2010) 1457 上是这样子描述的To compare the activity of materials with each other, the half-wave potential of each catalyst was estimated by determining the maxima of the derivatives of the reduction current. 不懂和8楼的朋友是用的方法一样的嘛? |

The more positive is V-onset ,the more active is the catalyst. V-onset is definded as the potential at which the ORR current is 5% of the measured at -0.3V,considering that the diffusion-limited current is parctically reached at that potential for all catalysts discussed in this work. 文章标题:Does CO poison Fe-based catalysts for ORR? 作 者:Jean-Pol Dodelet 期 刊:ELSEVIER Electrochemistry Communications 12 (2010) 628-631 希望对楼主有帮助! ![]() |
