    Chinese scholars "blow" a new method for preparing two-dimensional materials

     Time:2018-09-20

     
     
    Harbin Institute of Technology released a news on 18th, the school Weihai Campus materials Science and Engineering academy deputy professor Zhou WEIWI of the team in the field of macro preparation of two-dimensional materials made important progress.
     
    The research team is inspired by the traditional Chinese folk art "blowing sugar", proposing a new "gel-swelling" strategy and synthesizing 13 kinds of two-dimensional materials, including two-dimensional metal oxides, two-dimensional nitrogen-doped carbon, etc.
     
    First, the "Sol-gel" process is similar to the "syrup" viscous gel, and then the rapid heating produced by a large number of gases to "blow" the gel into an ultra-thin two-dimensional nano-film, so that the non-layered two-dimensional material can be produced, and no subsequent purification treatment.
     
    The method is universal, by selecting the appropriate metal precursor and calcination conditions to synthesize more two-dimensional materials, and the resulting two-D nano-film in lithium-ion batteries, sodium ion batteries and electro-catalysis and other fields have shown excellent performance.
