In Situ Controllable Loading of Ultrafine Noble Metal Particles on Titania

Herein we present a novel and facile approach to controllably load ultrafine noble metal nanoparticles on titania through in situ redox reaction between the reductive titanium(III) oxide support and metal salt precursors in aqueous solution. A series of noble metal/TiO2 nanocomposites with uniform metal dispersion, tunable metal particle size, and narrow metal particle size distribution were obtained.
