The evolution of MgAl layered double hydroxides (LDHs), prepared by the sol−gel method, throughout synthesis−crystallization−calcination−reconstruction process is thoroughly studied and compared to a coprecipitated analogue. X-ray diffraction transmission electron microscopy provide useful information about crystallinity morphology samples. It was found that crystal sizes do not necessarily decrease after calcination−reconstruction. Furthermore, aluminum coordination 27Al MAS nuclear...
Iron oxide nanoparticles are promising materials for many technological and environmental applications due to their versatile functionalization magnetic properties that allow a facile remote control, separation analyte recovery. In this contribution, the results of gold(III) sorption by naked DMSA-capped (DMSA = m-2,3,dimercapto succinic acid) magnetite discussed. Magnetite 8 nm diameter were first synthesized thermal decomposition iron(III) oleate followed ligand exchange reaction...
The XPS Fe 2p<sub>3/2</sub> core-level spectra of sodium hexacyanoferrate(<sc>ii</sc>) and nitroprusside.
BACKGROUND The technology for generating hydrogen using a photocatalyst has attracted considerable attention. Coupling TiO2 with other semiconductor oxides provided excellent results in decreasing recombination by transferring one of the charge carriers to another oxide. These photogenerated play key roles reduction and oxidation process photocatalytic production. Nevertheless, even if (e−-h+) are separated, reaction cannot happen without proper active sites. So, co-catalysts needed improve...
The hydration state and structural transformations of Ti films potentiostatically grown in 0.1 M NaOH are characterized utilizing EIS, Mott-Schottky XPS techniques. Variations presented the density donors, flatband potential fraction species measured by XPS, region characterization these associated with changes ratio different sub-oxides within passive film. Oxygen hydroxyl vacancies their respective formation rate constants estimated from EIS spectra fits a modified Point Defect Model. A...
We report the results of a VAMAS (Versailles Project on Advanced Materials and Standards) inter-laboratory study measurement shell thickness chemistry nanoparticle coatings. Peptide-coated gold particles were supplied to laboratories in two forms: colloidal suspension pure water and; dried onto silicon wafer. Participants prepared analyzed these samples using either X-ray photoelectron spectroscopy (XPS) or low energy ion scattering (LEIS). Careful data analysis revealed some significant...
