Recently, researchers at the Institute for Extreme Environment Quantum Physics, Institute of Solid State Physics, Chinese Academy of Sciences, successfully synthesized new nitrogen-hydrogen compounds. The material has excellent energy conversion efficiency and is of great significance in the application of energy substances. The results were published online on June 5 in the Journal of Chemical Physics (Vol.142, Issue 21). Nitrogen-hydrogen compounds have extremely high energy conversion efficiencies and less environmental pollution, and have potential application value in the development of energy materials. In addition, nitrogen and hydrogen compounds may also be the main components of the internal materials of giant planets such as Uranus and Neptune. Understanding the structure of the high pressure phase is an urgent need for current planetary geological research. However, in addition to ammonia, other compounds with NN bonds are generally metastable. For a long time, the synthesis of stable nitrogen and hydrogen compounds has been a challenging topic. Alexander Goncharov, a specialist of the Thousand Talents program outside the Solid Institute, and his team used diamonds to press anvil high pressure technology to change the intermolecular interactions and induce chemical reactions of the N2 and H2 mixture in the pressure chamber. The in-situ high-pressure Raman and infrared spectroscopy were used to identify the single-phase fluid structure under 9-11GPa pressure and the solid phase under higher pressure. When the pressure is above 47 GPa, Raman and infrared spectroscopy show new NN and NH vibration modes and change over time. Subsequently, the team cleverly combined the femtosecond photochemical experimental technique with the diamond anvil high pressure device and used femtosecond laser pulses to induce NH chemical reactions. It was found that similar NN and NH vibration modes can be induced at a lower pressure of 11 GPa with the participation of optical pulses. And when the pressure retreats to 3.5 GPa, the solid NH compound in the irradiated area still exists, and the unirradiated area around it shows a liquid. The researchers further revealed that the novel nitrogen-hydrogen structural material is NxH (0.5) through high-voltage synchrotron radiation and first-principles settlement. This is another important discovery by Alexander Goncharov following the synthesis of new forms of NaCl at high temperatures and pressures. This work has important research value in the fields of preparation of new energy materials, planetary geology and other fields. The project is supported by the National Natural Science Foundation of China and the “1000-person Project†of foreign professionals.
