Earth abundant metal catalysts stabilized by porous N-doped carbon
Final Report Abstract
The replacement of rare noble metals by earth abundant metals has been demonstrated successfully for homogenous catalysts in recent years. Reusable and nano-structured hydrogenation and dehydrogenation catalysts, based on abundantly available metals, with a broad scope in organic synthesis have been developed to a much lesser extent. The main criticism arose from the observation that earth abundant metal are much less active in nanostructured catalyst in comparison to noble metals. Polymer based SiCN and SiC materials combine material specific characteristics such as thermal robustness and corrosion resistance with easy processing and possible shaping or structuring at low temperatures in diverse organic solvents. This easy processing also permits the synthesis of highly active catalysts. In this project, we could show that nanostructured 3d-metal catalysts could be superior in activity and selectivity compared to noble metal catalysts. Two aims were reached as proposed namely 1. the development of novel catalysts based on porous N-doped SiC supports and 2. the design of active and selective 3d-metal catalysts for hydrogenation and dehydrogenation reactions.
