Ammonia decomposition over Ni catalysts supported on perovskite-type oxides for the on-site generation of hydrogen.

Ammonia decomposition has attracted increasing attention as a promising process for the on-site generation of hydrogen. In this study, Ni catalysts supported on perovskite-type oxides (ABO) were prepared and the activity for ammonia decomposition was examined. The Ni/ANbO (A = Na and K) and Ni/AEMnO (AE = Ca, Sr, and Ba) catalysts were less effective for this reaction.
