Investigation Of N1/MAI2O4 (M=Mg， Ca, Sr, Ba) for Catalytic NH3 Decomposition

摘要

NH3 is one of the candidates for Hydrogen carriers with good hydrogen density (17.8 wt% H2,120 kg H2/L in NH3liquid). NH3 decomposition catalyst is important to decompose NH3 into N2 and H2 for H2 generation (2NH3-> N2 +3H2 AH0 =- 46 kJ mol~(-1)). This catalytic NH3 decomposition reaction is known to have N associative desorption step as a rate-determining step, and tms step is influenced by using basic supports and promoters.
