The electrocatalytic reduction of nitrogen compounds. Part I.The electrochemical reduction of nitrite at a rotating platinum ring-disk 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.
