Photocatalysis on TiO2: insights from simulations

The tenth NCCR MARVEL Distinguished Lecture will be given by 
Prof.  Annabella Selloni (Princeton University) on Tuesday May 16, 2017, 4.15 pm, EPFL room MXF-1.

Abstract — TiO2-based photocatalysis for the degradation of pollutants and the splitting of water into H2 and O2 has been an important area of research for decades. In this talk I shall discuss recent applications of first principles electronic structure calculations and molecular dynamics simulations to understand materials properties and reaction mechanisms in TiO2-based heterogeneous photocalysis. Examples will focus on the structure and reactivity of anatase TiO2 aqueous interfaces, the behavior of charge carriers at the interface, and the formation and structure of so-called black TiO2, a promising functional material capable to absorb the whole spectrum of visible light.
