Technical Field
The invention relates to the technical field of inorganic nano material preparation, in particular to a preparation method of a TiO2 material with a continuous two-dimensional nanosheet structure.
Background
In recent years, with the rise of graphene materials, two-dimensional nanomaterials have attracted great research interests of broad researchers. The two-dimensional material has larger transverse dimension and thickness of atomic level, and can show the characteristics of high surface atomic ratio, anisotropic electrical property, adjustable band gap, high surface reactivity and the like. Compared with a bulk material, the coordination number, bond angle and bond length of atoms on the surface of the two-dimensional material are different, and abundant surface active sites can be provided for chemical reaction. Secondly, the specific surface area of the two-dimensional material is huge, and in the reaction process, the two-dimensional material has a larger contact area with a reaction solution, so that more reactants can be adsorbed, and the reaction can be promoted to be carried out more quickly. Again, the reduced thickness significantly reduces the distance that photogenerated charges migrate from the interior of the material to the surface of the material, thereby enabling faster reaction kinetics. And finally, the abundant defects on the surface of the two-dimensional material are utilized to carry out functional modification, so that the light absorption capacity of the material is improved, the charge separation and transfer efficiency is improved, and the surface oxidation-reduction reaction rate is accelerated. Due to unique electrical, optical and chemical properties, two-dimensional materials are widely applied to the fields of optoelectronic devices, catalysis, energy storage and conversion and the like.
TiO2Has the advantages of wide forbidden band width, no toxicity, good chemical stability and the like, and is widely applied to the fields of solar cells, ion batteries, photocatalysis, antibacterial materials and the like in recent years.
