Abstract

Ferric catalysts have been synthesized from the reactions between pre-infused ferric salts and simultaneous feeding of NaBH₄ solution into a H₂ generating reactor, and were proved to accelerate the subsequent H₂ generation reaction. It is found that there are competitive reactions during H₂ generation which lead to the formation of active FeB or inactive Fe(OH)₃. Also, the anion (Cl^- or NO₃^-) in the pre-infused ferric salt is crucial to the reaction pathway. The H₂ generation route using FeCl₃ as the pre-infused ferric salt shows excellent activity, resulting in a high H₂ generation efficiency (over 94%) and an average H₂ generation rate of 1.08 L/min.
