Researchers synthesized polymeric carbon monoxide (p-CO) under high pressure, revealing it as a high-energy-density material. This novel material rivals conventional explosives like HMX in energy content and shows potential as an advanced energetic material.

Area of Science:

  • Materials Science
  • High-Pressure Chemistry
  • Energetic Materials

Background:

  • Extended phases of molecular solids from light elements (low-Z) are a new class of materials.
  • Previous studies demonstrated their existence but produced microscopic quantities, limiting property characterization.
  • High-pressure synthesis is key to accessing novel material properties.

Purpose of the Study:

  • To experimentally verify if extended low-Z solids are high-energy-density materials.
  • To synthesize and characterize polymeric carbon monoxide (p-CO) at milligram scale.
  • To assess the energetic potential of p-CO.

Main Methods:

  • High-pressure synthesis using diamond anvil cells.
  • Milligram-scale production of polymeric carbon monoxide (p-CO).

Related Experiment Videos

  • Spectroscopic characterization of the synthesized material.
  • Assessment of decomposition properties and energy content.

    • Main Results:

    • Successful milligram-scale synthesis and recovery of polymeric carbon monoxide (p-CO).
    • Spectroscopic data indicate p-CO is a random polymer with lactonic and conjugated C=C structures.
    • p-CO exhibits an energy content comparable to or exceeding that of HMX (cyclo-tetramethylene tetranitramine).
    • Solid p-CO decomposes explosively into CO(2) and glassy carbon.

    Conclusions:

    • Polymeric carbon monoxide (p-CO) is confirmed as a high-energy-density material.
    • The material's properties make it a potential candidate for advanced energetic applications.
    • High-pressure synthesis enables the creation of novel energetic materials with significant potential.
