Abstract

Pt nanocrystal-supported titanate nanotubes as a photocatalyst were prepared by hydrothermal treatment and subsequent heat-treatment in H2 atmosphere (H2 reduction) of a mixture of these titanate nanotubes and H2PtCl6. TEM results showed that Pt nanoparticles (a few nm in diameter and 5 to 10 nm in length) with good crystallinity were entrapped inside titanate naotubes and were closely precipitated on the surface of titanate nanotubes. These Pt nanocrystal-supported titanate nanotubes possessed the high ability for HCHO decomposition.
