摘要采用兰尼镍催化剂和还原镍催化剂，研究了硝酸盐和亚硝酸盐在水中的加氢反应。为了确定反应级数，还原镍比雷尼镍更合适，因为雷尼镍表面有一个固有的氢，在反应过程中更容易被氧化。根据反应物的反应顺序，发现氢气在Ni表面的吸附弱于硝酸盐和亚硝酸盐。图形抽象
AbstractThe hydrogenations of nitrate and nitrite in water were investigated using a Raney Ni catalyst and reduced Ni catalyst. For determination of the reaction orders, reduced Ni is more appropriate than Raney Ni due to the fact that Raney Ni has an intrinsic hydrogen on its surface and is more readily oxidized during the reaction. Based on the reaction orders of the reactants, it was revealed that the adsorption of hydrogen gas on the Ni surface was weaker than those of nitrate and nitrite.Graphic Abstract
