摘要

摘要以廉价无毒的可溶性淀粉为碳前驱体，Pluronic共聚物为软模板，采用水热法合成介孔碳(MC-S)。在水热合成过程中，可溶性淀粉水解生成葡萄糖，葡萄糖通过氢键相互作用与Pluronic共聚物组装。葡萄糖进一步脱水并交联形成聚合物网络。将聚合物网络碳化后，最终得到MC-S。所得MC-S的比表面积为439 m2 g−1，孔径均匀，为4.5 nm，氧含量高达23.32%。MC-S由于含有氧官能团，对重金属离子的吸附性能优于FDU-15。

Preparation of mesoporous carbon from biomass for heavy metal ion adsorption

ABSTRACT Mesoporous carbon (MC-S) has been synthesized via a facile hydrothermal method by using cheap and nontoxic soluble starch as carbon precursor, Pluronic copolymer as soft templates. In the process of hydrothermal synthesis, the soluble starch can hydrolyze to give glucose, which can assemble with Pluronic copolymer through hydrogen bond interactions. Glucose further dehydrates and cross-links to form polymer networks. After carbonization of the polymer networks, MC-S can finally be obtained. The obtained MC-S has a specific surface area of 439 m2 g−1, uniform pore size of 4.5 nm as well as high oxygen content of 23.32%. The MC-S exhibits a good adsorption for heavy metal ions superior to FDU-15 due to the oxygen functional groups.
