TL;DR: In this article, the thermal stability and reducibility of oxygen-containing functional groups on the surface of nitric acid-treated multiwalled carbon nanotubes (CNTs) have been studied using temperature-programmed desorption and reduction (TPD and TPR) and high-resolution X-ray photoelectron spectroscopy (XPS).

TL;DR: In this paper, Nitrogen-containing carbon nanotubes (NCNTs) were prepared via pyrolysis of acetonitrile over cobalt catalysts at different temperatures to control the nitrogen content.

TL;DR: The anatase (101) surface shows a substantially higher activity, by an order of magnitude, for CO photo-oxidation to CO(2) than the rutile (110) surface, which tracks the bulk e-h pair lifetime difference for the two TiO( 2) modifications as determined by contactless transient photoconductance measurements on the corresponding bulk materials.

TL;DR: The interaction of water with ZnO nanoparticles has been studied by means of diffuse reflectance infrared spectroscopy (DRIFTS) and ultra-high vacuum FTIR spectroscope (UHV-FTIRS) and shows the expected isotopic shifts.

TL;DR: In this article, the active copper clusters consist of a bottom layer of mainly Cu+ atoms bonded on the oxygen vacancies (Ov) of ceria, in a form of Cu+−Ov−Ce3+, and a top layer of Cu0 atoms coordinated with the underlying Cu+ atom.
