Abstract

A novel kind of nano-sized TiO2 (anatase) was obtained by high-temperature (400–700°C) dehydration of nanotube titanic acid (H2Ti2O4(OH)2, NTA). The high-temperature (400–700°C) dehydrated nanotube titanic acids (HD-NTAs) with a unique defect structure exhibited a p-type semiconductor behavior under visible-light irradiation (\(\uplambda\ge420\) nm, E photon=2.95 eV), whereas exhibited an n-type semiconductor behavior irradiated with UV light (\(\uplambda=365\) nm, E photon=3.40 eV).
