Homogeneous synthesis of SiO2@TiO2 nanocomposites with controllable shell thickness and their enhanced photocatalytic activity.
Here we report the use of sulfuric acid as a catalyst for the facile and homogeneous synthesis of core-shell SiO(2)@TiO(2) nanocomposites using simple apparatus, under ambient pressure and temperature. The resultant SiO(2)@TiO(2) exhibits an ideal core-shell structure with uniform nanoscale TiO(2) coverage. The shell thickness of SiO(2)@TiO(2) can be conveniently tuned through adjustment of the...
متن کاملSingle crystalline tantalum oxychloride microcubes: controllable synthesis, formation mechanism and enhanced photocatalytic hydrogen production activity.
Single crystalline microcubes of a new tantalum compound, tantalum oxychloride (TaO2.18Cl0.64), have been fabricated hydrothermally in a concentrated aqueous solution of hydrochloric acid and acetic acid. They contain a superstructure and exhibit remarkably enhanced photocatalytic activities for hydrogen production due to the improved light harvest and facilitated charge transport.
متن کاملSurfactant-free Synthesis of CuO with Controllable Morphologies and Enhanced Photocatalytic Property
A green synthesis for nanoleave, nanosheet, spindle-like, rugby-like, dandelion-like and flower-like CuO nanostructures (from 2D to 3D) is successfully achieved through simply hydrothermal synthetic method without the assistance of surfactant. The morphology of CuO nanostructures can be easily tailored by adjusting the amount of ammonia and the source of copper. By designing a time varying expe...
متن کاملFabrication of Samarium-doped ZnO Hierarchical Micro/nanospheres with Enhanced Fluorescent Light- Driven Photocatalytic Activity
Samarium-doped ZnO hierarchical micro/nanospheres (Sm/ZnO) were synthesized via a facile and surfactant-free chemical solution route. The obtained products were characterized by field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX), UV–visible diffuse reflectance spectroscopy (UV-vis DRS) and photolumi...
متن کاملControllable Synthesis and Tunable Photocatalytic Properties of Ti3+-doped TiO2
Photocatalysts show great potential in environmental remediation and water splitting using either artificial or natural light. Titanium dioxide (TiO2)-based photocatalysts are studied most frequently because they are stable, non-toxic, readily available, and highly efficient. However, the relatively wide band gap of TiO2 significantly limits its use under visible light or solar light. We herein...
