Fabrication of TiO2/Pt core-shell particles by electroless metal plating

- The present work proposes a simple method for fabricating TiO2/Pt core-shell particles.
- TiO2 particles prepared by a sol-gel method were surface-modified with poly(diallyldimethylammonium chloride).
- Pt fine particles were pre-deposited on the surface-modified TiO2 particles by reducing Pt ions in the presence of the TiO2 particles.
- Pt shells were formed on the Pt-pre-deposited TiO2 particles by electroless metal plating method.
