2-3 nm fine metal nanoparticles (Au, Pt and alloyed Au-Pt) with a narrow size distribution were deposited on active TiO2 through a facile chemical reduction method. Compared to the bare TiO2, a remarkable enhancement of up to 10-fold for photocatalytic hydrogen evolution was achieved on the alloyed nanocomposites.
