Abstract :
We have found that N2 gas is subject to a cathodic reduction to form N3- ion in a molten chloride system. This new finding is encouraging us to consider the possibility of several energy conversion related electrochemical processes, i.e., thermally regenerative fuel cell with Li-N2 couple, ammonia synthesis from N2 and H2O, and electrochemical implantation of N atom into metal surface to form energy material. In order to provide available data for considering these possibilities, cathodic reduction of N2 gas, anodic oxidation of N3- ion and electrochemical surface nitriding reaction in molten chloride were investigated in detail
