Abstract


Silicate resource-rich, low-cost, unique physical and chemical properties, and has broad application prospects in the field of fluorescent material, ion exchange, catalysis, drug delivery, using a simple, green, economical method of controlled synthesis of functions on the dimension and the degree of crystallinity sexual silicate nanomaterials is of great significance for the development of its new value. The papers around the controlled synthesis of silicate nanomaterials modified nanotube material and removal of heavy metal ions, the lithium battery performance and other aspects of the application to expand the series of studies. Zinc silicate nanomaterials in ethanol / polyethylene glycol system synthesized amorphous zero-dimensional hollow ball, to explore the mechanism of its formation; better degree of crystallinity of the one-dimensional nanowires synthesized pure water phase system, The film of the two-dimensional layered nano; synthetic zero-dimensional and one-dimensional, two-dimensional zinc silicate nanomaterials used in heavy metal ion removal experiments, and achieved good results. At the same time to explore its removal mechanism, the degree of crystallinity of the material has a great influence on the removal of heavy metal ions, the zero-dimensional amorphous zinc silicate hollow sphere materials for the detection of heavy metal ions showed a good removal effect, under the same experimental conditions, Pb (II) ion removal rate was approximately 2 times the magnesium silicate hollow ball material; for better crystallinity zinc silicate materials, the removal efficiency of heavy metal ions with the corresponding dimension of the material presented, one-dimensional nanowire materials trivalent metal ions (Fe (III), Cr (III)) presents a better removal of the two-dimensional nano-thin films of divalent metal ion (Pb (Ⅱ), Cd (Ⅱ)) presents a better removal effect. For silicate nickel Nanomaterials, in ethanol / polyethylene glycol system synthesized zero-dimensional core-shell of the ball and hollow ball; synthesized by the high degree of crystallinity in the pure water system under strongly alkaline conditions, the thermal stability of a one-dimensional nano-tube material, and synthetic silicic acid nickel nanotube divalent nickel under hydrothermal conditions to obtain partially reduced to nickel nanocrystalline magnetic nanotubes, can be obtained by adjusting the hydrothermal reduction of the time and temperature parameters, the magnetic nickel adjustable silicic nanotube, and its applications in catalysis, drug delivery and other aspects to provide a better basis; synthetic silicic acid nickel nanotubes as a lithium battery cathode material applied to the field of lithium, showing better cycling stability, and its application in lithium. In addition, to further expand the ethanol / polyethylene glycol system, synthesized cobalt silicate core-shell ball and hollow ball, cadmium silicate series nanomaterials; explore in aqueous systems tellurite nanomaterials synthesis.
