Abstract

HMSN materials were synthesized using the rice husk. The characteristic of the obtained samples was performed with X ray diffraction (XRD), IR, SEM , TEM and nitrogen adsorption (BET). The analysis results indicated that HMSN had hollow spherical shape structures with the surface area of ​​72.4963 m²/g, pore volume of 0.104 cm³/g and pore size of 8.6771 nm. XRD shows the presence and amorphous nature of silica. The obtained HMSNs exhibited good ability to adsorb methylene blue, the maximum adsorption capacity reached 30.2146 mg/g.
