循环伏安扫速与扩散 求助？一篇文章审稿人提到的问题不知道如何解答，望诸位高手相助。1. Similarly, it is no correct to affirm that the process is a diffusion-controlled one only because the peak current grows in a linear fashion with square root of the scan rate. 审稿人说，不能仅从峰电位与扫速的开方成正比而推断出电化学过程为扩散控制。我的疑问是，还需要哪些其他的条件？2.Finally, the origin of non-zero intercepts on the current potential scan rate (square root) is unclear and against fundamental electrochemical relathionships (Randles Sevcik equation). this does require clarification and correction? has the background not (or incoreectly) subtracted? 这一条改如何回答？可能是什么原因？如果有相关文献麻烦给出。文章的内容是特殊形貌的 氢氧化镍 负载在 石墨烯 上用来做赝电容型电容器电极材料，三电极体系， 电解液 为KOH，集流体为泡沫镍。涉及到的图如下：相关的段落如下：Moreover, the shapes of the CV curves are similar as the scan rates increase from 5 mV s?1 to 40 mV s?1, showing anodic and cathodic peaks and indicating that a fast redox reaction occurred at the interface of the electroactive materials and the electrolyte. With increase in the scan rate, the measured specific current increases and the anodic and cathodic peaks shift positively and negatively, respectively. This is due to the diffusion extent of OH? into the XXX matrix at various scan rates. Besides, the anodic current (Ip) increase linearly with the square root of the scan rate (v1/2) at all scan rates (Fig. 6b), indicating the redox reaction of XXX in KOH solution is a diffusion-controlled process.在线等，非常感谢！查看更多7个回答 . 18人已关注
