The electrocatalytic reduction of nitrogen compounds Part I: The electrochemical reduction of nitrite at a rotating platinum ring‐disc electrode

The mechanism of the electrochemical reduction of nitrite has been studied at a rotating ring‐disc electrode. It is found that the reduction of nitrite to nitric oxide is a reversible process. The reduction of nitric oxide to hydroxylamine involves the intermediate HNO, from which dinitrogen oxide can be formed in a side reaction to the reduction process.
