Laponite-supported titania photocatalysts [PDF]

, 2008
This study builds on previous results published on the synthesis and characterisation of laponite-supported titania photocatalysts. Titania nanocrystals are prepared prior to addition to the clay dispersion, by a sol-gel synthesis incorporating a ...

Diblock Copolymer Nanoparticles Act as Nanoreactors for the Synthesis of Sterically‐Stabilized Inorganic Oxide Particles in Non‐polar Media

Angewandte Chemie, EarlyView.
Poly(lauryl methacrylate)‐poly(2‐hydroxyethyl methacrylate) (PLMA‐PHEMA) diblock copolymer nanoparticles prepared in non‐polar media serve as nanoreactors for the in situ synthesis of silica from tetraethyl orthosilicate (TEOS). A silica mass loading of 17% as judged by thermogravimetric analysis (TGA) produces a highly transparent dispersion, and ...
