Noei等人在超高真空条件下（UHV-FTIRS），通过FTIR光谱研究了CO与不同改性的多晶ZnO的相互作用。 在110K下将干净的无吸附质的ZnO纳米颗粒暴露于CO后，在2187cm-1处有强烈振动带，是CO与ZnO上的Zn2+位点结合所致。

2013年11月22日 · 用于研究金属表面的分子吸附,近些年来IR技术得到了突飞猛进的发展,应用范围也愈来. 愈广泛.由于CO具有电子受授性质,未充满的空轨道很容易同过渡金属相互作用,并且CO. 具有很高的红外消光系数,因此,以CO作为探针分子的研究报导较多. [2～7] .在这些报导中. 大都是有关BⅧ族金属,尤其较集中于Pt,Rh,Ni等少数几个元素,而对于Pd相对来说就不. 太多.而且对于这为数不多的研究中还多为纯金属Pd表面CO吸附态方面,兼而有少量有. 关不同载体催化剂的表征研究.

在研究红外光谱时通常有以下几种方法：（1）同位素交换法，使用14CO来交换12CO可以消除覆盖度的影响。 （2）程序升温脱附法，当CO吸附以后，对样品进行程序升温，可以获得CO在不同温度的吸附情况。 这个方法最为常用。 （3）恒温脱附法。 这种方法比较消耗时间，使用的比较少。 （4）吸附平衡红外法，这种方法研究了Pt、Pd、Ni、Au和Rh等负载金属。 使用这种方法可以获得不同覆盖度下CO的吸附热。 但这种方法需要对原位池进行特殊设计，以消除气相CO的 …

2024年9月9日 · The palladium oxide phase (PdO x) plays a critical role in catalytic methane oxidation and CO oxidation reactions. Precise characterization of supported PdO x by CO-FTIR spectroscopy is often accompanied by the reduction of PdO x by CO.

2017年10月20日 · The adsorption of CO on Au/TiO 2 catalysts was examined at room temperature using FTIR transmission spectroscopy. Adsorption was observed as (i) a sharp peak at ∼2100 cm –1 due to CO molecular vibration (the …

2020年9月1日 · FTIR studies under reaction conditions during CO oxidation were performed to determine the type of species and oxygen vacancies that are formed during the reaction, to better understand the nature of the mechanisms of the reaction under Ru-CeO 2 catalysts and to further to increase the catalytic stability of the prepared materials.

A series of Pt-Sn/Al 2 O 3 reforming catalysts were characterized with in situ FTIR of adsorbed CO method which is established in this study. And the adsorbed CO infrared peaks were obtained at room temperature on Sn/Al 2 O 3 catalysts that the mount of …

本课题组通过包括CO-FTIR、TEM和XPS等多种技术，深入研究了实验室和工业HDS催化剂的表面特性，结果表明只有ACO-CoMoS/ACO-MoS2与HDS选择性有良好的相关性 [57]。
