Recently, Sheng Zhigao’s team from the High Magnetic Field Science Center of the Hefei Institute of Material Science, Chinese Academy of Sciences used the SM1 superconducting magnet, a large scientific device with a steady-state strong magnetic field, to conduct research on special functional materials and found that strong magnetic fields can effectively control the rate of chemical reactions.
Reaction path and reaction products
.
Realizing the control of chemical reaction rate and products is the core issue of research in the field of chemistry and materials science
.
Like temperature and pressure, the magnetic field is an important basic thermodynamic parameter, which can directly act on the basic components of matter-the nucleus and extranuclear electrons through non-contact energy transfer, thereby affecting the physical and chemical properties of matter
With the help of the SM1 superconducting magnet and its supporting magnetron chemical reaction synthesis equipment, the research team has used the strong magnetic field center steady state strong magnetic field large scientific device SM1 superconducting magnet and its matching magnetron chemical reaction synthesis equipment.
The product has been systematically studied
.
The latest research results show that the magnetic field can effectively accelerate the reaction between trimanganese tetroxide and ferrous ions, so that the reaction speed of preparing hollow nanomaterials by the reaction of trimanganese tetroxide and ferrous ions is significantly increased, that is, the magnetic field It has an equivalent catalytic effect
The results of this series of studies on magnetron chemical reactions not only confirm the important role and great potential of strong magnetic fields in the regulation of chemical reactions, but also provide new paths and opportunities for the magnetron synthesis of special functional materials
.
