| Abstract: | In order to explore the preparation of inorganic porous materials by lignin as templates and improve the added value of lignin products, porous silicon oxide materials were prepared by sol-gel and roasting demould methods based on ethyl orthosilicate as a silicon source and lignin trimethyl quaternary ammonium salt as a template. Results showed that the lignin trimethyl quaternary ammonium salt existed in the compounds before calcination and porous materials after calcination had the characteristic absorption peak of SiO2, while the absorption peak of lignin trimethyl quaternary ammonium salt disappeared. The porous materials were characteristic of developed void space structure and aperture increased with the increment of the template amount. SiO2 PPP particles showed amorphous state. Specific surface area of porous materials decreased with the increment of template amount and the maximum was 354.5 m2/g. The aperture ranged from 2.7 to 5.6 nm and average aperture was 21.4 nm. The porous silicon oxide materials had good thermal stability and skeleton did not decompose even at 600~800 ℃. |
