In this study, microwave assisted ammonia decomposition reaction to produce high purity hydrogen over g-Al2O3supported molybdenum based catalysts were investigated and the effects of various promoters, rare-earth (lanthanum, cerium) alkaline-earth (calcium barium) elements on catalytic activity studied. Ammonia conversions 94% obtained unpromoted above 350oC at a flow rate 60 ml/min pure ammonia. The overall production per gram catalyst was found be 72.86 mmol/min.gcat with for 30 wt.% Mo loaded 350oC. apparent activation energy (Ea) values these around 85 kJ/mol. Among Ba Ce gave better performance below than Ca La optimum loading 4 them. Neither nitride nor carbide detected in spent form catalysts.
