The present study pointedly investigates the synthesis of mesoporous silica nanoparticles (sol–gel method) using four different surfactants (biosurfactants, CTAB, SDS and tween-80) under mild condition, was characterized by XRD (Low and wide angle), FTIR, FESEM, HRTEM, UV-VIS-NIR and XPS. The amorphous character of mesoporous silica (22.77O and 21.69O; XRD), hexagonal array with long-range ordered mesopores (SAXS), highest percentage of purity (47.9 and 56.09%; HRTEM-EDXS), perfect spherical shape with particle size (162 and 286 nm; FESEM), significant linkage of Si–O–Si (XPS) and absorption wavelength (271 and 262 nm; UV-VIS-NIR) affirmed with interesting outcomes in case of tween-80 and biosurfactant respectively, as compare to CTAB and SDS-mediated silica nanoparticles. In addition, the band gap of biosurfactant (5.29eV) and Tween-80 (3.78eV) mediated nanoparticles was also remarked lower as compare to other two surfactants as-synthesized nanoparticles. The promising formed silica nanoparticles could be greatly recommended to execute in heavy metals treatment, dye removal, anticancer activity, antioxidant activity, drug delivery, energy storage, etc.
