Abstract
Nanosized anatase TiO(2) single crystals with 18% {001} facets have a raised conduction band minimum by 0.1 eV, and exhibit photocatalytic activity both for generating *OH radicals and for splitting water into hydrogen that is markedly superior--by factors of 5.6 and 8.2, respectively--to reference ca. 3 microm anatase TiO(2) with 72% {001} facets.
摘要
具有 18%{001}面的纳米级锐钛矿 TiO(2)单晶使导带底升高了 0.1eV，并表现出明显优于参考约 3μm 锐钛矿 TiO(2)（72%{001}面）的光催化活性，分别提高了 5.6 倍和 8.2 倍，用于生成*OH 自由基和将水分解为氢气。
