摘要

KSF 粘土是一种具有高密度酸性活性位点的材料，非常适合用作具有出色活性的异相酸催化剂。本研究通过 X 射线光电子能谱和氨的温度编程解吸对 KSF-粘土进行了表征。此外，还利用漫反射红外傅里叶变换光谱法研究了乙醇、2-丙醇和乙酸分子在 KSF-粘土表面的吸附情况，以确定其热稳定性物种。KSF 粘土的性质与有机分子的吸附-相互作用过程之间的关系与其作为酸催化剂的性能有关。

Surface and physicochemical characteristics of KSF-clay in a liquid esterification process: The boundaries between heterogeneous catalyst and precatalysts support

The KSF-clay is a material that presents a high density of acidic active sites, ideal for being a heterogeneous acid catalyst with outstanding activity. For this study, KSF-clay was characterized by X-ray photoelectron spectroscopy and temperature-programmed desorption of ammonia. Additionally, studies of the adsorption of ethanol, propan-2-ol, and acetic acid molecules over KSF-clay surface to establish their thermal stability species were studied by diffuse reflectance infrared Fourier transform spectroscopy. The relationship between the properties of KSF-clay and the adsorption-interaction process with organic molecules is related to its performance as an acid catalyst.
