Fabrication of mixed-crystalline-phase spindle-like TiO2 for enhanced photocatalytic hydrogen production

The fabrication of heterojunction between different crystalline phases has been considered to be an effective strategy for promoting charge separation during photocatalytic process. Herein, the mixed-crystalline-phase (MC), spindle-like TiO2 was prepared


Synthesis of silicate-bridged ZnO/g-C3N4 nanocomposites as efficient photocatalysts and its mechanism†

Photocatalytic degradation of organic compounds on 20 semiconductors offers a viable approach to solve a variety of environmental problems.1 Among photocatalysts used, graphitic carbon nitride (g-C3N4) is a relatively novel, versatile and promising metal-


In-situ S-doped porous anatase TiO2 nanopillars for high-efficient visible-light photocatalytic hydrogen evolution

In-situ S-doped porous anatase TiO2 nanopillars are synthesized by a facile one-step thermal protection method. The prepared photocatalysts are characterized in detail by X-ray diffraction, Raman spectroscopy, N2 adsorption/desorption isotherms, UVevis di


Two-dimensional assembly structure of graphene and TiO2 nanosheets from titanic acid with enhanced visible-light photocatalytic

Highlights rGO@TiO2 nanosheet were obtained through ultrasonic exfoliation and calcination treatment. The composites exhibit higher hydrogen evolution yield than that of pure TiO2. The excellent performance mainly due to graphene and more active si


Synthesis of hierarchical Mn2O3 microspheres for photocatalytic hydrogen production

1. Hierarchical Mn2O3 microspheres with porous nanosheets were prepared. 2. The self-assemble process of the microspheres was studied. 3. The band structure of Mn2O3 microspheres is confirmed. 4. The hierarchical Mn2O3 microspheres displayed enhance


MgTiO3/MgTi2O5/TiO2 heterogeneous belt-junctions with high photocatalytic hydrogen production activity


High photocatalytic activity of carbon doped TiO2 prepared by fast combustion of organic capping ligands†

Carbon doping has been widely applied to modify TiO2 to improve photocatalytic activity and initiate visible light activity. Using oleylamine wrapped TiO2 nanomaterials as precursor, carbon doped TiO2 photocatalysts have been synthesized by control of hea
