NiO and NiO-CuO polycrystalline rodlike nanoparticles were confined stabilized within the channels of ordered mesoporous SBA-15 silica by a simple viable approach consisting in incipient wetness impregnation calcined support with aqueous solutions metal nitrates followed mild drying step at 25 °C calcination. As revealed low- high-angle XRD, N2 adsorption/desorption, HRTEM/EDXS H2 TPR analyses, morphostructural properties can be controlled adjusting their chemical composition, creating...
HAP solids were prepared with different Ca/P ratios and Na<sup>+</sup>cations before being characterized by XRD, XPS, LEIS, NMR, IR, TGA. Their acid–base properties then measured discussed in relation to the characterization results.
Ca<sub>3</sub>Co<sub>4</sub>O<sub>9+δ</sub> exhibits fast oxygen exchange kinetics rendering it a promising electrode for application as an air in solid oxide cells.
Resonance Raman spectroscopy is used in order to investigate the behaviour of Pd/γ-alumina (2 wt.%) catalytic combustion methane. Simultaneous spectroscopic and measurements allow an operando investigation catalyst under operational conditions. Temperature cycles were performed by alternately heating cooling system reaction conditions after various situ gaseous pre-treatments catalyst. Our results show that neither features nor conversion methane are influenced initial thermal activation...
LaMnO3 powder synthesized by glycine combustion synthesis with the rhombohedral and orthorhombic structures has been characterized combination of low energy ion scattering (LEIS) X-ray photoelectron spectroscopy (XPS), while electrocatalytic activity for oxygen reduction reaction is measured rotating disk electrode (RDE) method. Quantification surface terminations obtained LEIS suggests that crystallites are near thermodynamic equilibrium as atomic ratios compare well those morphologies...
Abstract The Guerbet reaction of ethanol to heavier products was performed over a series extensively characterized Sr‐substituted hydroxyapatites (HAPs) with different (Ca+Sr)/P ratios, and thus structural, textural, acid–base properties. properties were correlated the reactivity solids an optimal ratio between amount acid basic sites determined (ca. 4), whereas conversion mainly depending on specific surface area solids. stoichiometric 100 mol % sample (SrAp‐100) especially efficient in...
Ceria supported copper oxide catalysts were produced by a deposition-precipitation method, at high loading (up to >25 wt%). These materials demonstrated excellent properties for glycerol selective conversion lactic acid, with reaching up 87% selectivity acid of 74% (8 h reaction, 220 °C, under N2 pressure). also exhibited stability upon 5 successive reaction cycles. The formation crystalline CuO phase was in the nanocomposites Cu loading, elongated shaped particles formed on cerium surface....
Active phase of a catalyst: Using the 3D structural characterization environment around Mo atoms provided by X-ray absorption near-edge structure spectroscopy (left; spectrum MoK edge) and DFT calculations, molecular-scale TiO2-supported molybdenum oxide catalyst was defined.
