Title: Sol gel synthesis of doped titanates with specific modified stoichiometry

PROPHECYProzesskonzepte für die photokatalytische CO2 -Reduktion verbunden mit Life-Cycle-Analysis (September 2016- August 2019)

Since decades scientists try to bring carbon dioxide and water on a suitable semi-conducting materials under sunlight to reaction – still unsatisfied. PROPHECY is trying the following research approach: With the help of sunlight and the use of new catalyst material, CO2 and H2O should ecological and economical wise be converted into more valuable products like methan, methanol or syngas.

This project is a collaboration with colleagues at the LIKAT Rostock (photocatalytic CO2-reduction), TU Berlin (dry reforming at room temperature) and the KIT (sustainability analysis), industrial accompanied by the Siemens AG.

The aim of my particular subproject is the development of a new powder catalyst material based on the perowskite/ pyrochlore structure. My work is mainly focused on the stoichimetric synthesis of mixed oxides, especially calcium, strontium, bismuth and cerium titanates and their structural and photocatalytic properties.
