Nanocrystalline alumina was synthesized by using the sol−gel method with aluminum sec-butoxide as precursor. FTIR, TG, XRD, and crystalline structure refinement were used to analyze phase transformations their structures. When samples annealed at 200 °C, they had two nanocrystalline phases γ-boehmite γ*-boehmite, which same but different lattice parameters defect numbers in structure. After sample annealing above 400 γ*-boehmite transformed into γ-Al2O3 θ-Al2O3. The γ-alumina contained...
Iron-doped titania photocatalysts with different iron contents were prepared by using a sol−gel method in acidic media. The crystalline structures of the various phases calcined at temperatures ranging from 70 to 800 °C studied Rietveld technique combination XRD experiments. average crystallite size phases, lattice cell parameters, phase concentrations, and titanium cationic defects samples quantitatively determined. Both content calcination temperature strongly affected transformation...
Previous reports have demonstrated that carrier and exciton photocatalysis processes all occur with BiOBr photocatalysts. The photocatalytic properties of can be improved through optimizing any these processes. Herein, few-layered nanosheets expanded interlayer spacing oxygen vacancies been synthesized in situ applied for environmental remediation, specifically oil field produced wastewater decomposition. efficient activity is due to the synergistic effect both enhanced photocatalysis, which...
For the first time, creation of oxygen defects in crystalline structure WO3/SBA-15 catalysts and its correlation with Lewis acidity catalytic activity oxidation 4,6-dimethyldibenzothiophene (4,6-DMDBT) a model diesel were reported. All predominantly contained acid sites some WO3. The defect concentration increased from 1.67% to 16.66% per lattice cell unit, number varied 92 458 μmol/g as WO3 content 5 25 wt %. 4,6-DMDBT conversion was almost proportional both defects. Formic addition led...
In this paper, in situ synthesis of 3D-graphene/MnO2 foam composite using the combination chemical vapor deposition and hydrothermal method was reported for producing highly efficient graphene/metal oxide-based hybrid supercapacitors. The conformal growth exhibited high crystallinity low contact resistance, thereby improving charge transport efficiency electrolyte. Compared with previously described MnO2-based counterparts, porous structure 3D conductive graphene permitted electrolyte ions...
This work investigates biodiesel production via transesterification of Mexican palm oil with methanol catalyzed by binary solid base core–shell catalysts improved catalytic stability. A series CaO–ZnO mixed solids were prepared using an inexpensive co–precipitation method varying ZnO content from 5 to 20 mol%. Several factors, such as surface basicity, content, phase compositions, and thermal treatment the catalysts, all proven be crucial for good quality. Thermal could effectively remove...
Fe/TiO2 materials at 1 wt% Fe content have been prepared by the addition of aqueous solutions FeCl2 to titanium n-tetrabutoxide using hydrochloric acid (pH 3) as a hydrolysis catalyst. The obtained gel was thermally treated 200, 400, 600 and 800 °C. Characterization performed FTIR, UV–Vis, Mössbauer X-ray powder diffraction. FTIR spectra calcined samples showed presence highly hydroxylated TiO2. XRD patterns show coexistance brookite, anatase rutile TiO2 phases in up In sample °C only phase...
