摘　　要：Nitrogen is an indispensable element for life because it is a constituent of amino acids and a key constituent for various materials,as well as fine chemicals.Nitrogen molecules occupy~80%of the atmosphere but are chemically inert due to the strength of the NN triple bond and absence of polarity.This nonpolar nature makes N_(2)totally different from CO with an isoelectronic diatomic structure in reactivity.Thus,it was a challenge in chemistry to activate N_(2)to transform it into chemically usable molecules,such as NH_(3)and NO_(x).The Haber-Bosch(HB)process for the synthesis of NH_(3)from N_(2)and H_(2),which was established in 1913,marked the first practical chemical process of nitrogen fixation through extensive fundamental chemical research and much engineering ingenuity[1,2].This success of the industrial process saves human civilization from a hunger crisis.Since then,the HB process has been the predominant method for industrial NH_(3)production.The annual NH_(3)production has reached180 million tons globally,which makes it the most mass-produced chemical comparable to methanol.
