Because of the high strength of N≡N bonds, N2 is often employed as an inert gas. Now it has been shown that it can partly react to yield surface nitrogen species that facilitate C–O hydrogenolysis reactions on supported Ru catalysts.

N 2促进的加氢脱氧

由于N≡N键的强度很高，因此经常将N2用作惰性气体。现在表明，它可以部分反应生成表面氮，从而促进负载型Ru催化剂上的C–O氢解反应。
