其中一位審稿人提了幾條意見: 其中這三條想請問大家怎么回答比較好,本人是菜鳥,無奈審稿人提的問題我實(shí)在找不到文獻(xiàn)可以很好的回復(fù)他! 1.Electrodeposition of Pt and Ru metal particles in acid solution of 0.5 M H2SO4 containing H2PtCl4and RuCl3cannot proceed with 100 % efficiency due to the possible hydrogen evolution. The forming nuclei of nanoparticles will decrease the overpotential of hydrogen ions reduction. So, the process (hydrogen evolution on noble metal clusters) should proceed with a significant rate. Therefore,this suggests that the estimated masses of metal deposits are far from real mass of clusters. 2.In addition, to my opinion, very simple experiments could be done to make the interpretation more clear and the conclusion in the manuscript more reliable – the comparison of the EIS spectra in the presence and the absence of formic acid. 3.How about the degradation of catalysts in the presence of formic acid? The data on the reproducibility and stability of electrochemical responses should be provided. |

1. 如果我沒理解錯的話,你是按照電沉積曲線來算出沉積PT或RU的質(zhì)量吧.審稿人說的是沉積曲線中算出來的電量可能包括析氫的電量,因此你估算出來的質(zhì)量與真實(shí)質(zhì)量偏差大.建議做個ICP來確認(rèn)沉積物質(zhì)量. 2.審稿人說的是還要補(bǔ)做個小實(shí)驗:有燃料和無燃料時的交流阻抗來做個對比. 3.也是要補(bǔ)做個實(shí)驗來確認(rèn)電極的穩(wěn)定性,很多做燃料電池的文章里頭都做不同電位下的i-t曲線來說明電極的穩(wěn)定性,或者做個測試前后的SEM圖來比較看看電極的形貌差別. |
