Photocatalytic Activity of Hydrogenated TiO<sub>2</sub>
Photocatalysis is a promising advanced
water treatment technology, and recently the possibility of using
hydrogenation to improve the photocatalytic efficiency of titanium
dioxide has generated much research interest. Herein we report that
the use of high-temperature hydrogenation to prepare black TiO<sub>2</sub> primarily results in the formation of bulk defects in the
material without affecting its electronic band structure. The hydrogenated
TiO<sub>2</sub> exhibited significantly worse photocatalytic activity
under simulated sunlight compared to the unhydrogenated control, and
thus we propose that high-temperature hydrogenation can be counterproductive
to improving the photocatalytic activity of TiO<sub>2</sub>, because
of its propensity to form bulk vacancy defects
