Preparation method of mono-disperse silica mesoporous sphere material

The invention discloses a preparation method of a mono-disperse silica mesoporous sphere material in the technical field of inorganic materials, comprising the following steps: taking quaternary ammonium salt gemini surfactant as a template, organic solvent as an auxiliary solvent and organosiloxane as a silica resource, adjusting solution alkalinity and preparing the silica mesoporous sphere material with a structure in which pore canals are arranged to disperse from the centre of the sphere to the outer surface of the sphere. The silica mesoporous sphere material has single dispersed sphereappearance, with the relative standard deviation of the diameter being lower than 10 percent and the diameter of 70490 nm.
