Control of TiO2 crystal facets has attracted enormous interest due to the fascinating shape-dependent photocatalytic activity of this material. In this work, the effect of the ratio of {001} and {101} facets on the photocatalytic CO2-reduction performance of anatase TiO2 is reported. A new "surface heterojunction" concept is proposed on the basis of the density functional theory (DFT) calculations to explain the difference in the photocatalytic activity of TiO2 with coexposed {001} and {101} facets.
由于这种材料的迷人的形状依赖性光催化活性，TiO2 晶面的控制引起了极大的兴趣。在这项工作中，报道了锐钛矿 TiO2 的{001}和{101}晶面比例对光催化 CO2 还原性能的影响。基于密度泛函理论（DFT）计算，提出了一个新的“表面异质结”概念来解释具有共暴露{001}和{101}晶面的 TiO2 的光催化活性差异。
