Soft-Template Synthesis of Mesoporous Anatase TiO₂ Nanospheres and Its Enhanced Photoactivity.
Highly crystalline mesoporous anatase TiO₂ nanospheres with high surface area (higher than P25 and anatase TiO₂) are prepared by a soft-template method. Despite the high specific surface area, these samples have three times lower equilibrium adsorption (<2%) than Degussa P25. The rate constant of the mesoporous anatase TiO₂ (0.024 min-1) reported here is 364% higher than that of P25 (0.0066 min...
متن کاملSpecific Facets-Dominated Anatase TiO2: Fluorine-Mediated Synthesis and Photoactivity
Semiconductors crystal facet engineering has become an important strategy for properly tuning and optimizing both the physicochemical properties and the reactivity of photocatalysts. In this review, a concise survey of recent results obtained in the field of specific surface-oriented anatase TiO2 crystals preparation is presented. The attention is mainly focused on the fluorine-mediated hydroth...
متن کاملSynthesis of Spongelike Mesoporous Anatase and its Photocatalytic Properties
Mesoporous TiO2 has been prepared using a nonionic block copolymer (Pluronic P-123) as structure-directing agent with sol-gel method. Characterization of the product was carried out by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetry-differential scanning calorimetry (TG-DSC), Nitrogen sorption isotherms, and UV-vis absorpti...
