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 ...

The gas-phase chemical reaction between Ti(NMe2)4and NH3is a critical step in the Metallorganic Chemical Vapor Deposition (MOCVD) of TiN at low temperatures. We have examined this reaction using a flow-tube reactor coupled to an FTIR spectrometer. A sliding injector provides control over the ...
From the results of this study, it appears that H2 and H2O can induce an important error (close to 50%) on the CO and NH3 quantification by FTIR if they are not taken into account in the calibration method. We proposed a mathematical model which can be used with an Excel sheet. It ...
