Mesoporous hybrid shells of TiO<sub>2</sub>/NiO were prepared by sequential coating TiO<sub>2</sub> and NiO on SiO<sub>2</sub> nanospheres through a combined sol–gel hydrothermal process followed calcination template removal.
Yolk@shell nanostructures of Au@r-GO/TiO2 with mesoporous shells were prepared by a sol-gel coating process sequentially GO and TiO2 on Au/SiO2 core/shell spheres, followed calcination template removal, where the silica interlayer acts as not only to produce void space but also promote r-GO layer. The evaluation visible light photocatalytic activities in dye decomposition water-splitting H2 production demonstrated their superior performance, which indicates potential powerful photocatalysts.
Nanostructured hybrid shells of r-GO/AuNP/m-TiO2 were synthesized using SiO2 spheres as templates, followed by graphene oxide (GO) and Au nanoparticle (AuNP) deposition TiO2 coating, then post-treatments template removal calcination. Evaluation their photocatalytic activity degradation Rhodamine B (RhB) under the irradiation UV, visible light, simulated daylight demonstrated superior performance sandwich-like hollow shells, which could be attributed to porous nature enhanced charge...
Iron (oxyhydr)oxides play important roles in the fixation of toxic elements and also distribution nutrients for plants soils. Aakaganéite schwertmannite, as iron oxyhydroxides having an analogous tunnel structure, have been widely recognized Fe-rich environments. The objective this study was to examine formation akaganéite/schwertmannite via biooxidation 0.1 M ferrous solution containing only Cl−, SO42− or both anions with a Cl−/SO42− mole ratio 1, 3, 6, 10 by chloride-acclimated...
FeOOH as a naturally abundant, relatively low-cost and effective adsorbent have been gradually valued in wastewater field rich arsenic pollution, which can make for environmental remediation. In this study, samples included Gth1/Gth2 goethite, Aka1/Aka2 akaganéite, Lep lepidocrocite, were prepared used adsorbents, adsorption kinetic isotherm experiments of As(III) analyzed. Meanwhile, the effects pH, content, initial concentration electrolyte solutions on processes also discussed detail to...
Akaganéite (β-FeOOH) is a major iron oxyhydroxide component in some soils, marine concretions, and acid mine drainage environments. Recently, synthetic β-FeOOH has been found to be promising absorbent the treatment of metal-contaminated water. It recognized previous study that akaganéite could formed via FeCl2 chemical oxidation under specific conditions. Here we report novel simple method for bioformation from solution oxidized by Acidithiobacillus ferrooxidans LX5 cells at 28 °C. After...
Iron oxyhydroxides as the efficient scavengers for heavy metals have been extensively investigated in iron-rich acid sulfate waters presence of Acidithiobacillus ferrooxidans (A. ferrooxidans, an especially important chemolithoautotroph bioleaching and desulfurization coal). In this study, we observed morphology elemental composition cells stationary phase examined dynamic variation iron produced cultures A. incubated modified 9K medium initially including 0.15 M ferrous iron,...
Abstract The aim of this work is to study the performances isomeric α-, β-, and γ-FeOOH (goethite, akaganéite lepidocrocite, including five samples named as Gth1 Gth2, Aka1 Aka2, Lep, respectively) for removing hexavalent chromium (Cr(VI)) from aqueous solutions. adsorption mechanisms were explored by kinetic isothermal experiments. Adsorption efficiencies under different pH values, anions, levels adsorbate adsorbent also measured. Results showed that Cr(VI) FeOOH could be best described...
Iron oxyhydroxides for heavy metal treatment have attracted wide attention. In this work, iron of isomeric FeOOH (GpI) and tunnel-structural schwertmannite/akaganéite (GpII) were selected to study chromium (Cr(III)) adsorption removal from acidic aqueous solutions by batch experiments, under various reaction time, adsorbate/adsorbent level, pH anions. Adsorption processes well fitted pseudo-second-order kinetics (R2 = 0.992-0.999, except 0.829 Lep). Isotherm data could be Langmuir...
