關(guān)于雜多酸負載MCM-41 基體效應(yīng) 對XRD影響 希望大家?guī)蛶兔? 不勝感謝 已有1人參與

最近投的文章有一個審稿意見 ,我做的催化,雜多酸負載mcm-41,xrd做了小角和大角,小角是表明mcm-41載體結(jié)構(gòu)不變,只是有序性降低。大角是磷鎢酸在載體上分散均勻,沒有雜多酸的峰。然后審稿人問了這個問題,實在看不懂什么意思。也不知道是不是讓我機械混合 做大角xrd?看雜多酸分散度?希望大家?guī)兔纯词裁匆馑,然后怎么解?謝謝了!! 審稿意見如下:Catalyst is prepared by addition of 0.4286 g active material to 1 g support. So that would correspond to a dilution of the support by the active material, which will strongly absorb the X rays. The pore volume reduction can be significantly explained by the HPA volume (based on density it can be calculated). The X-rays modifications in figure 1 could be explained by the dilution effect rather than by the modification of the crystal structure of the MCM41. To be able to conclude they should have made a mechanical mixture of HPA and MCM41 at the same mass ratio, at least to take into account the matrix effect of high W loading on the X-rays.@jackdeng@lich666 |
