TL;DR: In this article, a stable radical species is generated on the surface of silica prepared by the sol-gel method from ethyl orthosilicate by the surface reaction between carbon monoxide and oxygen, while a small number of the radicals are observable on the silica sample evacuated at 950 K.

TL;DR: Although no formation of N 2 is observed, the process, which is at least partially reversible, offers some interesting possibilities for the removal of NO 2 from the gas phase.

TL;DR: In this article, the authors compared the oxidative coupling of benzene with that of methane on La2O3, CeO2, Pr6O11, and Sm 2O3 at temperatures greater than 1048 K.

TL;DR: In this article, the oxidation of methane has been investigated on lead hydroxyapatite (PbHAp), strontium hydroxymatic acid (SrHAp) and their binary mixtures at 873 K.

TL;DR: In this paper, the ESR spectra of the active oxygen radical (O 2 − ) formed on the hydroxyapatite (HAP) were analyzed and a quartet signal was derived from the interaction of an unpaired electron with three equivalent phosphorus atoms, which was attributed to the different active species for O 2 produced by the series of treatments: formation of O 2 − on thermally activated HAP, reaction of the O 2− species with propylene, heating at 673-973 K and treatment with O 2.
