Abstract

The catalytic properties of the passivated, reduced passivated, and fresh bulk molybdenum nitride for hydrazine decomposition were evaluated in a microreactor. The reaction route of hydrazine decomposition over molybdenum nitride catalysts seems to be the same as that of Ir/γ-Al ₂O₃ catalysts. Below 673 K, the hydrazine decomposes into N₂ and NH₃. Above 673 K, the hydrazine decomposes into N₂ and NH₃ first, and then the produced NH₃ further dissociates into N₂ and H₂. From the in situ FT-IR spectroscopy, hydrazine is adsorbed and decomposes mainly on the Mo site of the Mo₂N/γ-Al₂O₃ catalyst.
