Unusual ceria dispersion formed in confined space: a stable and reusable adsorbent for aromatic sulfur capture
TL;DR: An unusual ceria dispersion was achieved by using the confined space between template and silica walls in as-prepared mesoporous silica, for the first time, to exhibit high adsorptive desulfurization activity and excellent stability and reusability.

Reactions of Carboxylic Acids on Oxides: 1. Selective Hydrogenation of Acetic Acid to Acetaldehyde
TL;DR: In this article, the addition of platinum to the catalyst enhances selectivity and activity of aldehydes, based on the involvement of lattice oxygen (viz, a Mars and Van Krevelen mechanism) and the spillover of activated hydrogen from the platinum to an oxide.

Structure and composition requirements for deoxygenation, dehydration, and ketonization reactions of carboxylic acids on TiO2(001) single-crystal surfaces
K. S. Kim,Mark A. Barteau +1 more
TL;DR: In this article, the reactivities of TiO2(001) single-crystal surfaces for acetic acid decomposition were studied by TPD and XPS, and the surface structure and composition were varied by a combination of argon ion bombardment and annealing in order to investigate reaction selectivity and to identify the active sites responsible for adsorption and decomposition.
