Recovery of mesoporous silica from waste rice husk ash of biomass energy industry

摘要：

　　In this study,the mesoporous silica material was hydrothermally synthesized from the rice husk ash of biomass energy industry with cetyltrimethylammonium bromide (CTAB) as template agents.The structure and morphology of mesoporous silica material was investigated based on the analysis of X-ray diffraction (XRD),N2 sorption/desorption (BET),Fourier transformation infra-red spectrum (FTIR).The results indicated that mesoporous silica material was successfully prepared by substituting rice husk ash for the traditional silica source of tetraethyl orthosilicate,and the mesoporous silica material displayed pore sizes in the 2-4 nm range with specific surface areas as high as 363 m2/g.
