TL;DR: Silver nanoparticles of different morphologies were prepared using the polyol process and then dispersed on alpha-alumina and activity and selectivity were strongly dependent on the morphology of the silver nanoparticles.

TL;DR: In this article, a series of catalysts with different Au/Cu ratio and metal loading were used for epoxidation of propene oxide (PO) using TiO 2 -supported Au and Au alloy nanoparticles synthesized from pre-formed thiol-capped nanoparticles of controlled composition and size.

TL;DR: In this paper, the conversion of glycerol in gas phase and atmospheric pressure has been investigated over 10 wt.% Ni/γ-Al2O3 catalysts with nickel nitrate and pre-treated with hydrogen in the range of 623-1073 K. The resultant catalysts were characterized by N2-physisoption, H2-chemisorption, X-ray diffraction (XRD), TGA-MS, TEM, RAMAN, NH3-TPD, XPS, TPO-MS and XANES

TL;DR: Gold-copper alloy catalysts were prepared by impregnation of TiO2 (anatase) support with mixed chloride precursors and tested in the gas-phase epoxidation of propene as discussed by the authors.

TL;DR: Cobalt hydrotalcite-derived catalysts, doped with potassium, are active materials for the ethanol steam reforming reaction as discussed by the authors, which acts as a promoter of the ESR.
