• Playing ball with the Haber–Bosch process

    Dec 23, 2020In an eye-opening recent report it was demonstrated that the ammonia synthesis process could be powered mechanochemically in a simple ball mill laboratory experiment under the seemingly very gentle conditions of 45 C and 1 atmosphere. The mechanochemical ammonia yield reported was found to be significantly higher than the Haber–Bosch.
