Hierarchical layered titanate microspherulite : formation by electrochemical spark discharge spallation and application in aqueous pollutant treatment
An ultrafast and template-free method to synthesize three-dimensional (3D) hierarchical layered titanate microspherulite (TMS) particles with high surface area is reported. The synthesis makes use of an electrochemical ...
The origin of visible light absorption in chalcogen element (S, Se, and Te)-doped anatase TiO2 photocatalysts
We use first-principles calculations to clarify the origin of the visible light absorption in chalcogen element-doped TiO2. Our results show that interstitial doping is not the origin of visible light absorption under any ...
Ultrafast synthesis of layered titanate micro-spherulite particles by electrochemical spark discharge spallation
Bright sparks! Hierarchical layered titanate microspherulite particles with large specific surface areas (406 m2 g−1) and excellent adsorption abilities were quickly synthesized by a facile method that simultaneously ...
