Comprehensive IR study on acid/base properties of metal oxides
TL;DR: In this article, the absorption coefficients of pyridine for acidic sites and nitrobenzene for basic sites, estimated for various metal oxides by IR coupled with mass spectrometry, were within ±10% of the average value, which indicates that the integrated molar extinction coefficients could be used for semiquantification of acid/base sites of various oxides samples.

Superacidity and Catalytic Activity of Sulfated Zirconia
TL;DR: In this article, the acid property of sulfated zirconia, a so-called solid superacid catalyst, was precisely determined by ammonia temperature-programmed desorption with water vapor treatment and theoretical analysis.
Journal ArticleDOI
Analysis of Acidic Properties of Zeolitic and Non-Zeolitic Solid Acid Catalysts Using Temperature-Programmed Desorption of Ammonia
TL;DR: A method of ammonia temperature-programmed desorption (TPD) for analysis of acidic property of a solid was improved by introduction of a water vapor treatment method and development of a theory for calculation of ammonia adsorption heat from the TPD profile.

TL;DR: In this paper, a group study on the preparation of a MoO 3 /Al 2 O 3 catalyst was conducted to find predominant preparation parameters for better and reproducible catalyst preparations, and it was found that the surface area of the support was the most predominant preparation parameter for the dispersion of Mo oxide species.
