Decahedral Single-Crystalline Particles of Anatase Titanium(IV) Oxide with High Photocatalytic Activity

Abstract

Decahedral single-crystalline anatase particles prepared by a newly developed gas-phase process showed photocatalytic activities superior to those of P25 photocatalyst despite their relatively smaller specific surface area compared with that of P25, probably because of the low density of particle boundaries and crystalline defects.
