Herein, we report a systematic experimental and theoretical study about wide-ranged band gap tuning of protonated titanate nanotubes H2Ti3O7 (Ti-NT) by an easy ion-exchange method using low concentration (1 wt%) transition metal cations. To characterize describe the effect M doping (M = Cu2+, Ni2+, Co2+, Fe3+) on electronic, optical structural properties, semiconductors were analyzed combination methods density functional theory (DFT) calculations. The nanotube can be modified from 1.5 to...
A series of Ir and Au−Ir supported on TiO2 catalysts were prepared by deposition−precipitation with urea to study the activity stability these materials in CO oxidation reaction. Bimetallic samples using two approaches: one codeposition metal precursors other sequential deposition being iridium first be incorporated support. Samples submitted calcination air or reduction hydrogen thermal treatments. Nominal gold loading 4 wt %. characterized EDS, H2-TPR, HRTEM, HAADF, + O2 adsorption...
Methoxy and formate species resulting from methanol adsorption on Cu supported well-shaped CeO<sub>2</sub> are morphology-dependent.
NiO/Ni-doped ceria nanorods have been synthesized. Their unique structure combines specific composition and 1D morphology, which provide great improvements in their physical chemical properties.
Nickel (5 wt%) supported on Nd-doped ceria was studied as catalysts in the DRM reaction at stoichiometric conditions range of 600-800 °C. Ce1-x Nd x O2-δ supports with different contents (x = 0, 0.05, 0.1 and 0.2) were successfully synthesized. The role oxygen vacancies by incorporation Nd3+ into lattice investigated. These species quantified XRD Raman spectroscopy, showing a linear dependence function content. Ni/Nd-ceria prepared wet impregnation. Although formation vacancies, well...
A series of LaNiO3 materials were synthesized by the EDTA–citrate complexing method, modifying different physicochemical conditions. The samples calcined between 600 and 800 °C characterized XRD, SEM, XPS, CO-TPD, TG, DT, N2 adsorption. results evidence that although all presented same crystal phase, as expected, some microstructural superficial features varied a function calcination temperature. Then, tested catalysts CO oxidation process, reaction never thoroughly analyzed employing this...
We report a systematic investigation on the high-pressure CO2 capture performance of molten salts-promoted Mg–Al–palmitate layered double oxides (LDOs) as well an in situ DRIFT analysis to determine sorption mechanism these samples. The hydroxides (LDHs) coated with (Li–Na–K)NO3 salts were successfully prepared by coprecipitation and wet impregnation methods their have been systematically tested under different high pressures adsorption temperatures. Results showed stable (7–8 mmol CO2/g) at...
The surface properties of bimetallic Ni−Pt/SiO2 catalysts with variable Ni/Ni + Pt atomic ratio (0.75, 0.50, and 0.25) were studied using N2O decomposition reduction by hydrogen reactions as probes. Catalysts prepared incipient wetness impregnation the silica support aqueous solutions metal precursors to a total loading 2 wt %. For both model reactions, Pt/SiO2 catalyst was substantially more active than Ni/SiO2 catalyst. Mean particle size TEM about same (in range 6−8 nm) for all truly...
