Preparation and Characterization of Catalysts for Efficient Hydrogen Production via the High Temperature Water Gas Shift Reaction

This thesis deals with the synthesis and characterization of nanostructured high performance noble metal catalysts for Water Gas Shift (WGS) reactions using single and double flame spray pyrolysis (FSP) as a preparation method. FSP is considered an appropriate method for preparation of catalysts with high specific surface area, highly dispersed active centers and high stability in a single step. FSP derived catalysts for WGS reactions have not yet been investigated deeply. Another equally important objective of this thesis was to study hydrogen selective membranes and the integrated flame made catalysts using advanced x-ray based techniques at synchrotron light sources under real operating conditions in a micro-structured membrane reactor.
