Abstract: Synthesis of silica nanosphere is reported using tetrapropylammonium bromide and calcium carbonate as template for the first time. The physicochemical characteristics of the sample has been compared with the sample synthesized using cetyltrimethylammonium bromide and calcium carbonate. The results show that both the materials are similar, although mesoporosity appears only on the latter. The hollow sphere property is observed in calcined and 10 % dil. HCl treated samples. The weight loss due to calcium carbonate decomposition occurs at high temperature (800ºC). Thermogravimetry/ differential thermal analyses show that there is no organic amine inside the TPABr morphology and only a small amount (5 %) in CTABr sample. FTIR spectroscopic analysis shows the peak responsible for CaO⁻ in addition to the peak due to the T-O-T tetrahedral skeleton. Nitrogen adsorption does not show any significant result on the as-synthesized sample activated at 100ºC before adsorption.
