Solvent-controlled deposition of titania on silica spheres for the preparation of SiO2@TiO2 core@shell nanoparticles with enhanced photocatalytic activity
(Elsevier B.V., 2019-06-05)
Controlled synthesis of SiO2@TiO2 core@shell particles is important for effectively exploiting the unique properties associated with core@shell architecture and obtaining photocatalysts with enhanced photoactivity. Herein, ...
Phase Transformation in Titania Nanocrystals by the Oriented Attachment Mechanism: The Role of the pH Value
(Wiley-v C H Verlag Gmbh, 2009-01-01)
A new synthetic method for TiO2 nanocrystals starting from metallic Ti and hydrogen peroxide was developed. in order to obtain minimal interferences to evaluate phase transformation in the system. The results revealed that ...

Ligand exchange on CdSe nanoplatelets for the solar light sensitization of TiO2 and ZnO nanorod arrays
(Elsevier Science SA, 2019-01)
In quantum dot (QD) solar cells, the ex situ sensitization of wide band gap semiconductors (WBSCs) makes it possible to control the shape and the passivation of the nanosized sensitizer. Hence, ex situ techniques can be ...
