傳質(zhì)和再吸附對(duì)NH3-TPD的影響
|
|
|
固體酸催化劑測(cè)了NH3-TPD,但是審稿人覺得存在傳質(zhì)或者再吸附會(huì)延遲脫附時(shí)間,要我們證明實(shí)驗(yàn)結(jié)果沒有受到這些影響。師兄師姐們以前測(cè)酸強(qiáng)度酸量都是做個(gè)TPD,也沒被問過這個(gè)問題,屬實(shí)不知道該怎么辦,有知道的請(qǐng)指導(dǎo)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. |
