摘要

Nitrogen is an essential nutrient element for all living organisms,however in its sufficient molecular form,nitrogen could not be utilized to meet the crucial need for global food requirements or industrial production due to its strong non-polar N=N triple bond.Therefore,nitrogen fixation is an essential transformation but this only occurs in the nature with the help of nitrogenases [1].Although nitrogen can be artificially transformed into ammonia through the wellestablished Haber-Bosch process,the reaction is accomplished under drastic conditions,such as high temperature (300-500℃) and pressure (150-250 atmosphere),consuming the scarce fossil fuel and creating a large amount of greenhouse gas emission [2].In the view of the fuel shortage and global climate situation,achieving nitrogen fixation under mild conditions to overcome such high energy consumption is a crucial subject in chemistry and has fascinated the scientists for many years.
