摘　　要：氮在常压下是非常稳定的元素,以氮气分子形式存在。研究发现,氮在高温高压下能够形成聚合结构,这种结构具有极高的能量密度,而且分解产物为无污染的氮气,从应用角度上看,它能够作为新型环保高能量密度材料。随后,人们对其进行了大量的研究,得到了氮在高压条件下的相图,并且合成出立方偏转氮、层状聚合氮等结构。然而,纯氮聚合结构的合成条件比较严苛,在常压下很难保存。人们又转向分子结构氮和惰性气体氮化物等,希望能够得到常压下稳定的高能量密度氮结构。为此,针对目前高能量密度氮的理论和实验进展进行了简要的介绍,并对未来高能量密度氮的发展方向进行了探讨。Nitrogen is a highly stable element that exists in the form of nitrogen molecules under ambient pressure.Researchers have found that nitrogen can form polymeric structures under high temperature and pressure,which have extremely high energy density and decompose into pollution-free nitrogen.From the perspective of application,it can be used as a new type of environmentally friendly high-energy-density material.Subsequently,a large number of studies have been conducted on nitrogen,resulting in phase diagrams of nitrogen under high-pressure conditions and the synthesis of structures such as cubic gauche nitrogen and layered polymeric nitrogen.However,the synthesis conditions for pure nitrogen polymeric structures are relatively harsh,and it is also difficult to preserve them under ambient pressure.People have turned to methods such as molecular nitrogen and inert gas nitrides in the hope of obtaining stable highenergy-density nitrogen structures under normal pressure.This article briefly introduces the current theoretical and experimental progress of high-energy-density nitrogen and discusses the future development direction of high-energy-density nitrogen.
