The results presented herein unambiguously demonstrate that neither nanoparticulate carbon-supported gold, nor bismuth powder are active catalysts for the electrocatalytic dinitrogen reduction, but both can efficiently catalyze the electroreduction of NO₂^–, NO₃^–, NO, and NO₂ to ammonia in an aqueous electrolyte solution. Importantly, reduction of gaseous oxidized forms of nitrogen to NH₃ is more facile and occurs at significantly less negative potentials than that of nitrate and nitrite anions.

硝酸盐，亚硝酸盐和气态氮氧化物的电还原：氮还原研究中氨的潜在来源

结果呈现的这里明确地表明，无论是纳米颗粒的碳载金，也不铋粉末是电催化二氮还原活性的催化剂，但两者都可以有效地催化NO的电还原₂ ^-，NO ₃ ^-，NO，和NO ₂，以氨电解质水溶液。重要的是，相比于硝酸根和亚硝酸根阴离子，将气态的氧化形式的氮还原为NH ₃更容易并且在负电势下显着减少。
