Abstract:
Urea is a non-toxic, non-flammable hydrogen carrier which can be easily transported, stored and recovered from wastewater. Electro-oxidation of urea in the presence of a Ni catalyst is considered an effective approach for hydrogen production via urea decomposition. In this work, three different catalysts based on Ni (Ni/C, Ni(OH)2 and Ni/SWCNTs) were synthesized, characterized and used as catalyst incorporated in membrane electrode assembly (MEA) for urea electro-decomposition. The physico-chemical properties of catalysts were investigated by Scanning Electron Microscopy, Raman Spectroscopy, Chrono-amperommetry and Cyclic Voltammetry. Electrochemical measurements showed that Ni is promising alternative catalyst material for applications in wastewater treatment, hydrogen production and fuel cells.
