Influence of light on ad- and desorption processes on oxide semiconductor surfaces

Universität Rostock, 2022

Abstract: Metal oxide-based semiconductor materials have shown to be good contenders for the solar energy conversion reactions utilizing CO2 as energy storing agent. The influence of light on ad- and desorption of CO2 was investigated on different zinc oxide, titania and cerium zirconium oxide nanomaterials by means of DRIFTS and TPD method. The phenomenon of “IR-Blackening” was observed and found to be caused by interaction between phonons and electrons. No direct influence of UV-Irradiation on adsorption of CO2 on zinc oxide was confirmed, while on titania the preference changed under irradiation.
