Abstract

Surface-hydrogenated anatase TiO(2) (TiO(2)-H) nanowire-microspheres were prepared by converting protonated titanate nanotube to TiO(2)-H under a hydrogen atmosphere. We show that TiO(2)-H nanowire-microspheres have Ti-H and O-H bonds on their surface and exhibit improved visible-light absorption and highly enhanced photocatalytic activity.

摘要

表面氢化锐钛矿 TiO(2)（TiO(2)-H）纳米线-微球是通过在氢气气氛下将质子化的钛酸盐纳米管转化为 TiO(2)-H 来制备的。我们表明，TiO(2)-H 纳米线-微球在其表面具有 Ti-H 和 O-H 键，并表现出改善的可见光吸收和高得多的光催化活性。
