[求助] 测量OER Tafel斜率问题 已有2人参与

我们文章中采用从LSV曲线读取数据直接作图得到Tafel斜率,但是审稿人觉得这不是稳态的测试结果,给出了如下审稿意见。请问这要怎么测啊?CA/CP的测试方式是不是类似https://jingyan.baidu.com/article/17bd8e5254f5ba85aa2bb860.html这儿提到的测试方法。
4. Tafel slopes are wrong. In definition, Tafel lines should be drawn from the curves that are 100% iR drop free. Hence, authors must obtain the Tafel slopes by other means (e.g, CA/CP or EIS).
测试的电压范围、扫描速率等等参数需要怎么设置啊?
谢谢各位

你好!你可以私信我邮箱,我发一篇文献你看,里面有如何用CA或者CV测试Tafel。We recommend reporting the Tafel plot produced by both CV and CA (or CP) to verify the accurate measurement of activity. As shown in Figure 10c, theTafel plot measured by CV (iR- and background-corrected) overlaps with the steady-state CA (iRcorrected),[83] indicating both of these two methods can reliably measure the OER activity of IrO2 nanoparticles.
