Abstract
Nano-sized anatase TiO(2) 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 TiO(2) nanosheets with 88.4% {001} facets.
摘要
纳米级锐钛矿 TiO(2) 具有暴露的 {001} 晶面，由层状质子化钛酸盐前体制备而成。由于其小尺寸（约 11nm）和大表面积（155m(2)g(-1)），具有 26.1% {001} 晶面的晶体表现出明显优于参考的约 76nm 锐钛矿 TiO(2) 纳米片（88.4% {001} 晶面）的光催化活性。
