A study has been made on the production and analysis of mesoporous silica using sodium silicate derived from silica sand found in West Sumatra. Sodium silicate from silica sand was used as raw material to synthesize mesoprous silica together with non-ionic surfactant P104. The raw materials were based on their high abundance as a natural resource in West Sumatra and the use of non-ionic surfactants is cheap and does not produce harmful by-products. Sodium silicate is a white solid with a SiO2/N2O mole ratio of 0.58, which is in the range of commercial sodium, and aging time on the morphology and pore size of silica was studied using X-ray diffraction (XRD), Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), adsorption-desorption isothermal analysis (BET) and Transmission Electron Microscopy (TEM). The hexagon spherical regular mesoporous silica with a pore diameter of 5.2 nm was obtained at mixed pH 5 and aging time for 6 hours. © 2025, Rasayan Journal of Chemistry, c/o Dr. Pratima Sharma.
