The work identifies for the first time important defects in the surface of TiO2 (anatase) using a combination of advanced spectroscopic techniques with atomic resolution and theory. The understanding of the TiO2 surface at the atomic level is paramount for different research areas, where TiO2 plays a pivotal role, such as solar-to-energy conversion ( solar cells and water splitting) as well as heterogeneous catalysis. The work is the result of Dr. James W. Ryan ( former Ph.D. student in Prof. Palomares group and now Tenure Track researcher at NIMS) overseas visit during his Ph.D. at ICIQ to establish fruitful collaboration with the two centres. Prof. Palomares will visit NIMS in 2016 after been awarded with a visiting Professor Grant by NIMS.
