Abstract

original image

Hoch hinaus: Das Leistungsvermögen von TiO2-Anatas-Kristallen in Energie- und Umweltanwendungen korreliert normalerweise mit den exponierten TiO2-Kristallfacetten. Von größter Bedeutung ist die Erhöhung des Anteils hoch reaktiver Oberflächen. Ein neuer Gasphasen-Oxidationsprozess mit TiCl4 als Vorstufe ergibt nun TiO2-Anatas-Einkristalle, die hauptsächlich hoch indizierte {105}-Facetten aufweisen, die Wasser photokatalytisch spalten.
