The CZC catalysts were characterized and their long-term stability and selectivity

This work entails catalytic hydrogen production which has an extensive application in both mobile application and energy production. Methanol is a high density molecule with excellent H/C ratio and has been reported to be a good hydrogen carrier. In addition, no risk is associated with methanol since it lacks C-C bonds and will thus operate at low temperatures. This work entails developing a catalyst coupled with the construction of a good reformer in the field of catalysis. The first part of this work involved the catalyst Cu/ZrO₂/CeO₂ which was investigated based on varying copper contents. The CZC catalysts were characterized and their long-term stability and selectivity were investigated, and the kinetic data were determined. CO is generated in the process and renders Pt electrode of the fuel cell inactive. This led to the use of ammonia which had the disadvantage of hydrazine production. A new type of ammonia cracking catalyst was investigated in this study, which unlike the conventional catalyst is not based on metal. The zirconium oxynitrides was prepared and tested for their activity in ammonia decomposition. A long-term study was carried out on the best catalyst and no hydrazine was detected. The result provides a basis for the further improvement of the catalyst.
