Nano-assembly technology based on porous nanomaterials is a hot topic in the field of nanomaterial structure.This technology plays an important role in the development of new structures and the application of materials.Halloysite nanotubes are the most promising natural nanomaterials developed in recent years.Nano-assembly technology is applied to the study of halloysite nanotubes,which has important application value for the development of such nanotubes.In this paper,the preparation technology of transform the inner surface of halloysite by other substances is explored.The structure and performance of the method are analyzed by using the relevant representation method.It has been found that vacuum impregnation is more effective in allowing the addition of components to enter the nanotube.In addition,the tracer technique has been used in the study,and the position of the tectonic material is clearly shown.The nanotubes modified by the preparation technique have been used in different adsorption particle systems.It is found that the adsorption of metal ions in the water has the best use of results.Especially,Halloysite after ammonium salt modification has excellent properties of adsorbed vanadium.At the same time,it is found that with the increase of the number of ammonium salts in the tube,the adsorption performance gradually increased,and the maximum adsorption capacity reached 80.9 mg/g.Furthermore,it is investigated that the desulfurization and CO2 treatment performance of this kind of nanotubes.The above research provides some experimental basis for the development of halloysite nanotubes.
