6-1-4 電気分解を用いたアンモニア廃水処理と水素回収

抄録

Ammonia (NH₃) is a serious pollutant in agricultural fields and hydrogen carrier with high hydrogen capacity of 17.8wt.%. Therefore, effective NH₃-cracking technique should be established for both of the clean energy supply and wastewater treatment to protect the environments. Electrolysis of ammonia-water solution is one of attractive methods as the effective NH₃ cracking. The theoretical electrolysis voltage of 0.06 V is only 5 % of 1.23 V of the electrolysis voltage of water (H₂O). In this study, the electrolysis of ammonia on Pt-black electrode was investigated under various conditions.
