Development of catalysts for H2 production by ammonia decomposition under mild reaction condition

Nowadays NH3 has been regarded as one of the potential H2-storage materials. In this research, novel supported metal catalysts for producing renewable hydrogen by ammonia decomposition under mild reaction condition was developed. For that purpose, basic hydrotalcite-like compound was used as precursor for Mg-Al oxide support. It was revealed that 5 wt%Ru/Cs2O/Mg-Al-oxide converts 51% of NH3 even at 573 K with a space velocity of 3000 h-1. Furthermore, Ru-free Ni catalyst, CeO2/15wt%Ni/ Mg-Al-oxide, was found to exhibit almost complete conversion of NH3 even at 773 K.
