Ammonia has recently attracted a great deal of attention as an alternative energy source carrier because clean hydrogen can be produced via ammonia electrolysis without the emission of COx. In this study, we prepared the Pt electrode by electrodepostion method, and the electro-catalytic oxidation behaviour of ammonia was studied in alkaline media. The electrode was characterized by qualitative and quantitative analysis. To discover the optimal structure and the effect of ammonia concentration, the bulk pH value, reaction temperature, and applied current of ammonia oxidation were investigated using potential sweep and galvanostatic methods. Finally, the preparation of PtED catalyst is used as anode electrode in an ammonia electrolysis system. Ammonia electrolysis was conducted using a zero-gap type cell, and it was shown that highly pure hydrogen was produced with a high energy efficiency over 80 %. |
