Development of Solid Catalysts for Ammonia Decomposition

Ammonia synthesis is one of the most important achievements of the chemical industry. Recently however, ammonia decomposition has attracted increasing attention, not only for cleanup of syngas from coal or biomass gasification but increasingly also for the on-site production of CO_x-free hydrogen for fuel cell applications. Accordingly, suitable catalysts for both low and high temperature applications are required. To allow ammonia decomposition at low temperature, we concentrate on supported noble metal catalysts and study factors as micro- and mesoporosity of the support and promoters of the group of alkaline and alkaline earth metals. Besides, metal carbides and nitrides are considered for high temperature applications.
