Disclosed is a method of synthesizing hollow silica having the size of micrometers from sodium silicate. The method includes fabricating a polystyrene organic template from polystyrene latex, (B) cleaning the polystyrene organic template, (C) exchanging media by using a water-base medium, introducing the cleaned polystyrene organic template and sodium silicate, and preparing a silica-coated organic template by performing an acidic hydrolysis reaction, and (D) cleaning the silica-coated organic template included in the water-base medium by using water. The size of the organic template is adjusted by controlling an amount of introduced AIBN included when the organic template is fabricated. The cleaning of the organic template is preferably performed by using water (HO). The method further includes (B) removing the organic template by using THF and (F) cleaning the hollow silica having no organic template.
