Abstract

In recent years, the advantages of microstructured devices for chemical reactions have been demonstrated most impressively. The application of microstructured reactors has gained significant importance in chemical synthesis and analysis [1]. The spectrum of chemical conversions, carried out successfully in microstructured reactors, includes many catalytic reactions. Supportless onedimensional nanostructures were recently recognized as durable catalysts [2]. Due to their low diameter, nanowires provide a very large surface area without the need for a high-surface-area support. Moreover, it is expected that these structures can reduce all degradation pathways discussed for nanoparticles such as Ostwald ripening. To use their full potential in applications, however, nanowires need to be integrated efficiently in different device architectures
