傳質(zhì)和再吸附對NH3-TPD的影響
|
||
|
固體酸催化劑測了NH3-TPD,但是審稿人覺得存在傳質(zhì)或者再吸附會延遲脫附時間,要我們證明實驗結(jié)果沒有受到這些影響。師兄師姐們以前測酸強度酸量都是做個TPD,也沒被問過這個問題,屬實不知道該怎么辦,有知道的請指導一下。以下是審稿意見: The use of NH3-TPD should be discussed in more depth by the authors. As Prof. R. Gorte demonstrated in this technique it is essential to ensure that there is no re-adsorption or mass transfer limitations of the probe molecule as this can lead to artificial delay of the elution time. He argued that it is better to limit our discussion of TPD to total acidity rather than strength of acid sites as the latter can be misleading if transfer of molecules varies from one sample to the next. For this reason, I would suggest the authors to show proof that these TPD results are not caused by mass transfer or re-adsorption problems. |
