TLDR
In this paper, the genesis of the high activity of zirconium oxide promoted by platinum and sulfate ion (Pt/SO 4 2− -ZrO 2 ) for skeletal isomerization of butane and pentane in the presence of hydrogen is studied in terms of the interaction of the catalyst with molecular hydrogen.About:

Sulfated zirconia and its modified versions as promising catalysts for industrial processes
Ganapati D. Yadav,Jayesh J. Nair +1 more
TL;DR: In this article, the chemistry and engineering aspects of sulfated zirconia catalyst and its modified forms are discussed, and the surface properties of these catalysts can be further modified in conjunction with noble or transition metals as promoters as well as with carbon molecular sieves.

Structural and Catalytic Characterization of Solid Acids Based on Zirconia Modified by Tungsten Oxide
TL;DR: In this article, the authors showed that the W centers are in a distorted octahedral oxygen environment, even after dehydration at 673 K, in all WOx-ZrO2samples (2-21 wt.% W) oxidized at 1073 K.
Journal ArticleDOI
Sulfated zirconia as a hydrocarbon conversion catalyst
TL;DR: A survey of the literature data suggests that the preparation technique, initial calcination and final catalyst treatment play important roles in determining catalyst activity as mentioned in this paper, and that the final treatment probably is the most important and least controlled step in most studies to date.

Strong interactions in supported-metal catalysts.
TL;DR: Spectroscopic measurements indicate that an electron is transferred from the cation (such as Ti(3+) or Nb(4+)) to the metal particle, which leads to profound changes in the catalytic and chemisorption properties and the morphology of the metal particles.

Structure of acid sites on sulfur-promoted iron oxide
TL;DR: In this paper, the sulfur oxide species of a chelating organic sulfate structure, structure II, which is responsible for the generation of strong acidity, has been proposed, in which two covalent SO double bonds play an important role.
