RT,最好是南京地区，不然长三角地区也可以。目的是要测出催化剂的表面酸性，L酸与B酸。粉末状。
各位虫友好,我最近想用NH3-FTIR来表征分子筛催化剂的B酸和L酸,但是前两天做实验,用的分子筛是HZSM-5(200),分别在200,300,400,500,600℃下采集背景和NH3脱附的图谱,得到的图这个样子的,感觉不像是出峰,所以在想是不是实验步骤出问题了?请各位大神帮帮忙,给予指点,谢谢啦! HZSM-5(200).jpg...

Therefore, the study of adsorbed ammonia at high temperature is a key step for the understanding of its role in the NH3-SCR catalytic cycle. We employed different spectroscopic techniques to investigate the nature of the different complexes occurring upon NH3 interaction. In particular, FTIR ...
NH3 adsorptionNH3 competitive adsorbed FTIR method is proposed for investigating the interaction between confined species and acidic sites. Results indicate aromatic cations formed in SAPO-34 cages. The cations have much higher extinction coefficient than the corresponding aromatics. They cause the new ...
