High-Energy Nitrogen: Breakthroughs and Challenges

Recent years have witnessed significant progress in the research of polynitrogen compounds as high-energy-density materials. Scientists have successfully synthesized compounds containing hexazine rings and conducted in-depth studies on their structure and stability. However, the synthesis and stability of polynitrogen compounds remain a significant challenge, with factors such as quantum tunneling effects playing a crucial role. Future research will focus on overcoming the challenges in synthesis and stability to develop safer and more efficient polynitrogen high-energy materials.
