    Squeezing Molecules Guides Chemistry

    Neutron-scattering studies reveal surprising formation of ammonia after acetonitrile is turned into graphitic polymer, opening doors for catalyst-free industrial reactions at room temperature.

      Acetonitrile is a compound observed in outer space around a young star system. The reactions illustrated may be produced by extreme pressure and temperature events, such as asteroid and meteor collisions. Scientists mimicked these conditions on earth and discovered the formation of graphene-like multilayered onion nanostructures.

    The Science

    Unexpected results could lead to room temperature production of new materials that change how we produce, store, and use energy. Pressure, not heat, is the key. An interdisciplinary team subjected acetonitrile, a stable compound containing carbon, hydrogen and nitrogen atoms, to high pressure at room temperature. The result? A layered polymer carbon akin to graphene. The team from Oak Ridge National Lab, the Center for High Pressure Science &Technology Advanced Research in Beijing, and the Carnegie Institution of Washington were surprised to find this catalyst-free method also produced ammonia.  

    The Impact

    The finding opens the door for new ways to synthesize carbon nanomaterials at low temperature. It also sheds light on possible natural chemical processes on distant planets as well as comets and meteors.

    Summary

    Extreme pressure can determine the chemical evolution of inorganic and organic carbon-based molecules. Neutron scattering experiments combined with Fourier-transform infrared Raman and solid-state nuclear magnetic resonance spectroscopy revealed a room-temperature method for making a polymer from a simple acetonitrile precursor, without a catalyst, by employing high pressure (>25 gigapascals, or about that found 650 kilometers below the Earth’s surface). Reactions with acetonitrile usually require a strong base and metal catalyst. The catalyst-free method “squeezed” chemicals to break stable bonds between carbon and hydrogen atoms, transferred hydrogen from carbon to nitrogen, and formed an amino group, dimer, chain, and nanoribbon. Then ammonia was ejected to create a graphene-like structure. Thus, using high pressure—rather than high temperature—opened the door to new opportunities for synthesizing carbon nanomaterials at room temperature without a traditional chemical catalyst. Intriguingly, because acetonitrile is found in space, catalyst-free, high-pressure chemistry suggests it may be possible to discover complex hydrocarbon-containing compounds in impact craters of distant planets.
