Sol–gel synthesis highly porous titanium dioxide microspheres with cellulose nanofibrils-based aerogel templates

• Highly porous titanium dioxide microspheres was synthesized.
• Cellulose nanofibrils based aerogel microspheres are good template.
• The modified porous TiO2 microspheres showed a super-hydrophobic property.

Highly porous titanium dioxide microspheres had been prepared via a template-assisted sol–gel process with cellulose nanofibril aerogel microsphere template. The modified porous titanium dioxide microspheres showed a typical super-hydrophobic property. The method reported in this study may be applied to fabricate other inorganic materials with desired porous structure.

Highly porous TiO2 microspheres were synthesized by a sol–gel method using cellulose nanofibril microsphere aerogel as the template.Figure optionsDownload as PowerPoint slide
