Photocatalytic CO2 reduction

Photocatalytic CO2 reduction

Internship Description

In this project, the student will prepare dye-sensitized metal oxide nanoparticles for photocatalytic carbon dioxide reduction. Specifically, nanoparticles consisting of, for instance, titania, zirconia, and ceria will be dyed with different anthracene derivatives as photosensitizers and the photophysical properties such as energy and electron transfer processes will be studied by steady-state and time-resolved spectroscopy. Furthermore, the efficiency of sensitized nanoparticles will be tested in photocatalytic reduction of carbon dioxide and in photovoltaic devices, namely in dye-sensitized solar cells.
