Hollow porous BiOCl microspheres assembled with single layer of nanocrystals: spray solution combustion synthesis and the enhanced photocatalytic properties.

The hollow porous microspheres assembled with BiOCl nanocrystals were successfully synthesized via a facile spray solution combustion synthesis method. The microstructure, morphology, absorbance, optical properties of the samples were investigated in detail. The results show that hollow porous BiOCl microspheres have narrow band gaps (2.

Hierarchical nanostructures of γ-TaON flowers for enhanced visible light driven photocatalytic activities.

Hierarchical nanostructures of single phase γ-TaON flowers have been successfully synthesized using a simple wet-chemical route in addition to subsequent thermal nitridation. These flower-like particles exhibit an obvious improvement in visible-light-driven photocatalytic activity.
