Nanostructured surfaces offer a unique option in increasing effective surface area and therefore feature a huge technological potential in context of a variety of applications with one of them being the field of catalytically active surfaces. Within this field, taking into account aspects like energy conservation as well as green technology in general, biomass gasification represents an intriguing research area. In order to take advantage of this technology an efficient catalyst based tar reduction with respect to a product gas is of crucial importance. Goal of the project proposed here is to promote the development, synthesis, and characterization of catalytically active materials/surfaces in the context of water vapor reformation of tars in the product gas of a biomass gasification process within a temperature range of 700-900 °C. The work itself will be based on very promising preliminary results achieved for a nanostructured complex composite system: Ni5TiO7/TiO2/Ti. The catalytic activity of this system along with other potential candidates will be evaluated by means of dedicated experimental procedures. The intension is to gain fundamental insight into the growth mechanism of the corresponding nanostructures. Such knowledge would allow for the development and synthesis of optimized nanostructures that feature high catalytic activity, an increased lifetime, and potential regenerative properties.
