最近一篇文章大修，审稿人的提问，NiCo2O4/PPy-12电极材料在扫速20mV s-1下有明显氧化峰，但是作为对比的材料NiCo2O4/PPy-6和 NiCo2O4/PPy-24在扫速20mV s-1曲线形状扭曲，而且没有明显的氧化还原峰，审稿人认为随着PPy负载量的增加，CV曲线的变化没有规律。如何给出合理的解释？感谢大家！
In Fig. 6, the CV curve of NiCo2O4/PPy-12 sample at a scan rate of 20 mV s-1 show obvious oxidation and reduction peaks. In Fig. S2, the CV curves of both NiCo2O4/PPy-6 and NiCo2O4/PPy-24 samples at scan rate of 20 mV s-1 show distorted shape and no obvious oxidation peaks can be seen. Are there any mistake? If there is no mistake, it means that with the increase of PPy on NiCo2O4, the change of CV curves is irregular. Please give an explanation.
