Dec 1, 2015 · Here we report a very facile and reproducible method for the synthesis of CSNs with a control of particle morphology, crystallinity and phase selectivity, and provide important insight into the effect of core@shell configuration on the photocatalytic and optical properties of SiO 2 @TiO 2 CSNs.

Jan 1, 2017 · The broadened diffraction peak of SiO2 nanoparticles extracted from Lapindo mud volcano indicates an amorphous state of SiO2. From XRD characterization, it is known that SiO2@TiO2 that majority phasae is TiO2 anatase. The main peak of TiO2 anatase is found for SiO2@TiO2 nanoparticles at 2θ = 25,32o.

Nov 1, 2024 · In this work, nanostratified structures composed of alternating layers of silica (SiO 2) and titania (TiO 2) were proposed and fabricated using plasma-assisted electron beam deposition.

Feb 3, 2020 · In this study, a novel ternary heterostructure pholocatalyst, ZnIn 2 S 4 @SiO 2 @TiO 2 (ZIS@SiO 2 @TiO 2) was successfully prepared by simple sol–gel and solvothermal methods. The SiO 2 nanospheres were used as a support to prevent the aggregation of TiO 2 nanoparticles efficiently.

This review aims to encompass the available methods of synthesis of SiO2-TiO2 composite with modifiers or dopants, the application and known chemical and physical properties in surfaces such as glass, mortar and textile, including aspects for the development of this material.

Mar 24, 2018 · Results indicate that using SiO2 improved the durability of the TiO2 coating without affecting its photocatalytic properties. Thus, this novel SiO2@TiO2 coating shows potential for developing long-lasting, self-cleaning and air-purifying construction materials.

Mar 24, 2018 · Use of silicon dioxide (SiO2) and titanium dioxide (TiO2) have been widely investigated individually in coatings technology, but their combined properties promote compatibility for different...

Jan 21, 2012 · The field-dependent photoconductivity of TiO2/SiO2 nanocomposite shows nearly 300 folds more than that of TiO2 nanoparticle for a field of 800 V/cm. The use of titania–silica in photocatalytic process has been proposed as an alternative to the conventional TiO2 catalysts.

Dec 5, 2018 · Carbon-coated SiO 2 /TiO 2 (SiO 2 /TiO 2 @C) nanosheets consisting of TiO 2 nanoparticles uniformly embedded in SiO 2 matrix and a carbon-coating layer are fabricated by using acidified titanosilicate JDF-L1 nanosheets as template and precursor.

Oct 7, 2021 · In this work, we investigate the high-temperature microstructure evolution and photonic behavior of nanomultilayer SiO 2 /TiO 2 samples up to 1710 °C. It is shown that they can increase the diffuse reflectivity of absorbing or reflective substrates (e.g., graphite, tungsten) to values exceeding 75% across an almost 1000-nm-wide wavelength range.
