Thin Coatings of α- and β-Bi2O3 by Ultrasonic Spray Coating of a Molecular Bismuth Oxido Cluster and their Application for Photocatalytic Water Purification Under Visible Light.

Abstract

Invited this month's cover picture are the groups of Professor Michael Mehring and Professor Marc Armbrüster at Chemnitz University of Technology. The cover pictures shows a graffiti displaying a distinctive part of the city center of the town. The artwork is oversprayed with the letters "TUC" (Technische Universität Chemnitz) using an bismuth oxido cluster from solution to obtain a yellow semiconductor coating of bismuth oxide, used to degrade the medicinal drug ethinyl estradiol under visible light irradiation.
