摘要：
Photocatalytic hydrogen production and pollutant degradation provided both great chances
and challenges in the field of sustainable energy and environmental science. Over the last
few decades, we have witnessed the fast growing interest and effort in developing new
photocatalysts, improving the efficiency and exploring the reaction mechanism at the
atomic and molecular level. Owing to the relative high efficiency, nontoxicity, low cost and
high stability, TiO2 becomes one of the most extensively investigated metal oxides in
semiconductor photocatalysis. Fundamental research on well characterized single crystals
using ultrahigh vacuum based surface science techniques could provide key microscopic
insight into the underlying mechanism of photocatalysis. Here, elementary steps of
photocatalytic reactions on TiO2 surfaces studied with surface science techniques such as
two-photon photoemission spectroscopy and temperature programmed desorption will be
presented.
