Breakthrough in High-Energy Density Materials: Novel Nitrogen Allotropes

Recent years have witnessed remarkable progress in polynitrogen chemistry. Researchers have synthesized various novel nitrogen molecular structures, such as hexazine rings and caged nitrogen molecules, using high pressure and other methods. These molecules possess extremely high energy densities, promising to become next-generation high-energy materials. However, the synthesis and stability of polynitrogen compounds remain significant challenges, with factors such as quantum tunneling effects profoundly influencing their properties. This research not only expands our understanding of nitrogen but also opens new avenues for developing novel high-energy materials.
