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.

纳米结构表面在增加有效表面积方面提供了独特的选择，因此在各种应用中具有巨大的技术潜力，其中之一是催化活性表面领域。在这一领域内，考虑到节能以及一般的绿色技术等方面，生物质气化是一个有趣的研究领域。为了利用该技术，关于产物气体的基于有效催化剂的焦油减少是至关重要的。本项目的目标是在700-900 °C的温度范围内，促进生物质气化过程产物气体中焦油的水蒸气重整的催化活性材料/表面的开发、合成和表征。这项工作本身将是基于非常有前途的纳米结构的复杂复合材料系统：Ni 5 TiO 7/TiO 2/Ti取得的初步结果。该系统的催化活性沿着其他潜在的候选者将通过专门的实验程序进行评估。其目的是获得相应的纳米结构的生长机制的基本见解。这些知识将允许开发和合成优化的纳米结构，其具有高催化活性，增加的寿命和潜在的再生性能。
