Abstract

The invention relates to silicate and provides a preparation method for hollow silicate, in particular to a simple and effective method for preparing hollow silicate under solvothermal conditions. The method comprises the following steps: synthesizing silicon dioxide nanospheres: mixing tetraethoxysilane, water, ammonia water and ethanol by volume ratio of 1: (0.25-2): (0.25-4): (4.25-68) of tetraethoxysilane to water to ammonia water to ethanol, and washing the obtained products after reaction to obtain the silicon dioxide nanospheres; and adding the silicon dioxide nanospheres, urea, dihydrate-2-hydroxy-5-sulfo-benzoicacid and nitrate hexahydrate in water and ethanol, and cooling the obtained solid product to room temperature after reaction, and washing the obtained solid product to obtain the target product, i.e. the hollow silicate.

Description

technical field

[0001] The invention relates to a silicate, in particular to a method for preparing hollow silicate by solvothermal. Background technique

[0002] With the research and application of nanomaterial preparation technology and new properties, nanomaterials have become one of the hot spots that people pay attention to. Now people are not satisfied with simple nanomaterials. Nanomaterials in hollow form are important components in materials. Due to its unique application value, hollow materials have attracted extensive attention of researchers. The existing hollow structure preparation methods mainly include hard template method (S.W.Kim, M.Kim, W.Y.Lee, T.Hyeon, J.Am.Chem.Soc.2002, 124, 7642) and soft template method (H.L.Xu, W.Z.Wang, Angew.Chem.Int.Ed.2007, 46,1489), but there are many defects in these methods, need to remove template as hard template, and soft template can introduce surfactant and cause product impurity, meanwhile, the whole The operation p...
