Surface-hydrogenated anatase TiO2 (TiO2-H) nanowire-microspheres were prepared by converting protonated titanate nanotube to TiO2-H under a hydrogen atmosphere. We show that TiO2-H nanowire-microspheres have Ti-H and O-H bonds on their surface and exhibit improved visible-light absorption and highly enhanced photocatalytic activity.
