Lightweight aggregates, drug delivery and energy storage are some of the numerous applications of silica nanoparticles. Amorphous silica was extracted from corn stalk using the sol-gel hydrothermal method and nanostructured using Hexadecyl trimethyly ammonium bromide (CTAB) as template. The crystallographic structures of synthesized silica nanoparticles was characterized using X-Ray Diffraction (XRD). Functional groups was determine using fourier transform infrared (FT-IR) techniques, specific surface area was determine using the Brunauer Emmett Teller (BET) method. The presence of SiO2 was confirmed by Energy dispersive X-ray (EDX), surface morphology and particle size was examine using scanning electron microscope (SEM) and transition electron microscope (TEM). This study provide a silica nanoparticles sourced from agricultural biomass for cutting-edge applications including drug delivery.
