TL;DR: The present work critically reviews the formation of crystalline nanoscale titania particles via solution-based approaches without thermal treatment, with special focus on the resulting polymorphs, crystal morphology, surface area, and particle dimensions.

TL;DR: In this article, the influence of elevated reaction temperatures on the activity, long-time stability, and deactivation behavior of Au/TiO 2 catalysts for CO oxidation was studied by kinetic and in situ IR measurements in the temperature range 80-180°C, both in an idealized, H 2 -free reaction atmosphere and in a H 2-rich gas mixture.

TL;DR: In this paper, the authors used operando XAS measurements in the near (XANES) and the extended (EXAFS) Au LIII edge as well as in situ diffuse reflectance FTIR (DRIFTS) spectroscopy in combination with kinetic measurements in a further attempt to identify the nature of active Au species responsible for the high activity of Au/CeO2 catalyst in the low-temperature water gas shift (LT-WGS) reaction.

TL;DR: In this paper, the influence of pretreatment on the activity and deactivation behavior of a high surface area 4.5 Wt.% Au/CeO 2 catalyst during low temperature CO oxidation reaction was studied in a multi-technique approach.

TL;DR: In this article, the effect of H 2, CO 2 and H 2 O on the activity, stability and deactivation behavior of an oxidatively (O400) and a reductively (H400) pretreated 4.5% Au/CeO 2 catalyst in the water gas shift (WGS) reaction at 300°C was studied by kinetic and spectroscopic measurements.
