It is considered as the most possible material for replacing silicon, however the characteristic that band gap is zero limits the development of graphene.With graphite alkenes
Seemingly, black phosphorus is a kind of two-dimensional material of single element, there is Van der Waals force between layers, and difference can be obtained by way of removing
The flat crystal of the number of plies.Black phosphorus not only possesses superhigh current carrying transport factor (200~50000cm of class graphene2/ V*s), and
Its band gap can adjust (0.3eV~2.0eV) by the number of plies, compensate for the deficiency of graphene.In addition to this, black phosphorus material internal
Electronics and photon show the anisotropy of height in lamella, therefore are suitble to the development of future electronic industry.
The research of black phosphorus at present is in the starting stage, and development is slower, is primarily due to currently without a kind of simple height
The synthetic method of effect.1914, Bridgman heated white phosphorus to 200 DEG C, finds black phosphorus for the first time under the pressure of 1.2GPa
In the presence of;Nineteen fifty-five, German chemist Krebs, H. under normal pressure, use mercury as catalyst, and using a small amount of black phosphorus as crystal seed,
At a temperature of 370 DEG C, white phosphorus is converted to black phosphorus;1981, Tokyo University scientist Maruyama, Y. used the simple substance melted
Bismuth dissolves white phosphorus, and then Slow cooling recrystallization synthesizes acicular black phosphorus.However, the severe toxicity and ignition quality of white phosphorus limit
The application of these methods.2007, Nilges, Tom utilized Au, Sn and SnI4As combination catalyst, under vacuum conditions, add
Hot red phosphorus obtains black phosphorus to 600 DEG C, but the introducing of noble metal improves production cost and the purity of black phosphorus decreases;
CA105133009A, CA105460910 and CA105565289 also disclose the improvement to this method, but former to temperature control and red phosphorus
That expects is more demanding, and there is catalyst choice certain limitation (to be only limitted to Au, Sn, I2Or its product that reacts to each other) and simultaneously
It does not reuse;2010, Cheol-Min Park utilized high energy ball mill, synthesized the composite material of red phosphorus and black phosphorus, but
High-energy ball milling method is difficult accurately to control the pressure and temperature of inside reactor, influences the controllability of preparation process.Therefore at present
More commonly used synthetic method is high pressure (10kbar) method, but these methods have high requirement to laboratory apparatus.
