Topic: Photocatalysis with GaN
Time: 10:00 a. m., March 1st (Wednesday)
Location: Conference Room B, BLDG 909
Abstract
GaN and its related alloys currently are receiving more and more attention in the field of photo-catalysis due to their widely tuneable direct band gap, their chemical stability, the possibility to provide both p- and n-type doping, the easy implementation of high quality nanowire growth on various substrates, and the advantageous position of the GaN conduction and valence band edges with respect to the Fermi level of common co-catalysts and electrochemical redox levels. In the presentation, I will review some basic photo-catalytic properties of GaN functionalized with organic monolayers and Pt nanoparticles. In addition, a possible solution to overcome the spectral mismatch between the wide band gap of semiconductors such as GaN and the solar spectrum will be presented.
