Synthesis of nano-sized anatase TiO2 with reactive {001} facets using lamellar protonated titanate as precursor

Nano-sized anatase TiO2 with exposed {001} facets was synthesized from lamellar protonated titanate precursor. Owing to small size (ca. 11 nm) and high surface area (155 m(2) g(-1)), the crystals with 26.1% {001} facets exhibited markedly superior photoactivity to reference ca. 76 nm anatase TiO2 nanosheets with 88.4% {001} facets.
