From a study of the electrocatalytic reduction of nitrate on Pt and Rh electrodes over a wide pH range, HNO3 is suggested as the only reducible species in nitrate reduction on Pt, whereas both HNO3 and the nitrate anion are reducible on Rh. Rh is the more active catalyst of the two because it can activate nitrate even if no protons are available in solution. This is an important insight into the development of more effective nitrate reduction catalysts.
通过在较宽pH范围内对铂和铑电极上硝酸盐的电催化还原进行研究，表明在铂上进行硝酸盐还原时，HNO₃是唯一可还原的物种，而在铑上HNO₃和硝酸根阴离子均可还原。铑是两者中活性更高的催化剂，因为即使溶液中没有质子，它也能活化硝酸盐。这对于开发更有效的硝酸盐还原催化剂具有重要的启示意义。
