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

Abstract

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 m² 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.
