審稿意見回復求助~。。。。。。

RT 近期一篇文章收到如下的審稿意見,小弟能力有限,實在是有些拿捏不好其用意何在,到底應該如何回復?還請各位大俠指點一二 具體意見如下: 1)針對的文章中具體的句子:Comments to the Author Pg 13, Line 19 “In addition, we note that several large nanoparticles were observed in the two monometallic samples due to the inevitable aggregation in impregnation; however, in bimetal oxides families, this negative phenomenon of particles aggregation is largely prevented, signifying the contribution of bimetal oxides systems toward the improvement in the morphological features with well dispersion and smaller particle size.” 2)審稿人的具體意見: (1)The authors should take great care in drawing such grand conclusions from TEM analysis. The method is inherently sporadic in its sampling and it is important that one conscientiously looks across the entire TEM grid in order to ensure fair sampling and proper statistics. (2)In addition to the possible shortcomings of the ineffective sampling, the authors have drawn an incorrect conclusion with respect to the dispersion of the formed bimetallic nanoparticles. I do not agree that bimetallics from coimpregnation will lead to increased dispersion over monometallics. One could argue that that the metallic precursors (in solution) interact with the support surface differently, and thus have different nucleation sites leading to one metal showing a higher dispersion. This may be the case with Pd versus Ru as monometallic Ru is shown to form smaller particles. However, this would give the two extreme cases for a bimetallic: small particles for Ru and larger ones for Pd. The authors have stated that the co-impregnation of both metals led to increased dispersion beyond that of the expected limiting case of the small Ru particles. 個人理解如下:1)原稿所用語言有些過大,有些絕對化; 2)審稿人不認同基于HRTEM進行粒子統(tǒng)計,因為中間可人為控制的因素較多,難于服眾! 3)但是最后這一段實在是有些拿捏不好,因為如果是從審稿人所說的粒子同載體相互作用的角度來說的話,得到的應該是同其相反的結果;再者,審稿人所說的相互作用貌似只是關注到了最初始的制備過程,但后續(xù)的熱處理及其他預處理過程的影響并未提及,但這些處理過程的影響或許更大(我們的觀點) 相應的論點如下:1)弱化相關表述,只提HRTEM可以提供直觀的粒子尺寸和分布,不擴展至分散度的范疇,同時修改相應的描述; 2)認為雙金屬體系的確可以改善粒子的分散性能,但如果按上述所說觀點的話,似乎就沒有必要再跟審稿人關于這個問題進行討論和反駁。 以上只是目前的觀點,但總覺得無必勝的把握! 還請各位大俠不吝賜教! 字數(shù)比較多,還請各位可以耐心看完 ! 救命的文章! |
