Novel Pt-poor catalysts for the electrocatalytic O2 reduction based on modified, nanostructured metal oxides

Projektdetails

Beschreibung

These studies will be performed in a very systematic approach, via a deliberate tailoring of nanostructure, porosity and chemical composition of the catalyst and/or its support on the one hand correlated with its electrocatalytic performance on the other. This objective shall be reached by combining i) a synthetic approach to prepare mesoporous high-surface area oxide materials of variable structure and composition, a very controlled ap¬proach of doping the material with carbon and nitrogen, the formation of a stable highly porous carbon support, which was recently developed in the laboratory of the(Salzburg group, and ii) the use of a wide range of sophisticated electrochemical, microscopic and (in situ) spectroscopy methodic approaches to study electrocatalytic reactions under up to fuel cell relevant reaction conditions developed in the laboratory of the other applicant (Ulm group) in a highly iterative way. In combination, these meas¬urements will provide detailed information on the correlation between materials properties and catalytic performance as well as mechanistic information, and thus provide a basis for further target-oriented im¬provement of the catalyst materials.
