Abstract

Shine a light! High-purity tungstic acid hydrate nanotubes and nanoporous-walled WO3 nanotubes (see picture) were synthesized. The platinum-loaded WO3 nanotubes show a photocatalytic activity in the degradation of acetaldehyde about three and eight times greater than that of commercial WO3 particles and nitrogen-doped TiO2, respectively.
