摘要:

在可持續(xù)發(fā)展已成為全球各國(guó)共識(shí)的今天，合理且高效地研發(fā)及利用可再生生物質(zhì)能源成為國(guó)內(nèi)外各大課題組研究的熱點(diǎn)及方向。而納米纖維素作為典型的生物質(zhì)可再生材料，將其應(yīng)用到環(huán)境治理領(lǐng)域成為再好不過(guò)的選擇。同時(shí)，以納米纖維素為基體制備的氣凝膠作為第三代氣凝膠材料，具有高孔隙率、高比表面積、低密度、低介電常數(shù)和較高的吸附性等性能，在染料吸附、油污吸附、重金屬離子吸附、CO2氣體吸附等吸附領(lǐng)域有著廣闊的應(yīng)用前景。綜述了納米纖維素的制備方法、納米纖維素基氣凝膠的制備工藝及其在吸附領(lǐng)域的應(yīng)用，探討了納米纖維素基氣凝膠在研發(fā)中存在的問(wèn)題，展望了納米纖維素基氣凝膠在吸附領(lǐng)域的未來(lái)發(fā)展方向。

Abstract:

Nowadays, sustainable development has become the consensus of all countries in the world. Reasonable and efficient research and development of renewable biomass energy for reuse has become a hot research topic and direction of major research groups at home and abroad. As a typical biomass renewable resource, nano�瞔ellulose has become a good choice in the field of environmental treatment. Meanwhile, nano�瞔ellulose based aerogel as the third generation aerogels, has the advantages of high porosity, high specific surface area, low density, low dielectric constant and high absorbability. It has broad application prospects in dye adsorption, oil adsorption, heavy metal ions adsorption, CO2 gas adsorption and other fields. The preparation methods of nano�瞔ellulose, the preparation technology of nano�瞔ellulose based aerogel and its applications in the field of adsorption are reviewed in this paper. The problems existing in the research and development of nano�瞔ellulose based aerogel are discussed, and the future development direction of nano�瞔ellulose based aerogel in the field of adsorption is prospected.
