Synthesis of Biomass-Derived Mesoporous Carbon with Super Adsorption Performance by an Aqueous Cooperative Assemble Route

Exploring the suitable precursors that interact with the surfactant via hydrogen bonding is an important task for the green synthesis of mesoporous carbons (MCs). Boron doped mesoporous carbon and its derived super adsorbent are synthesized by a reproducible and low-cost hydrothermal method. beta-Cyclodextrins and boric acid were employed as the environmentally friendly carbon precursor and dopant, respectively, which give the mesoporous carbon a certain doping amount and super capture ability. This method not only permits the biomass-derived compounds to participate the self-assembly process but also reduces the potential industrial scale production cost and avoids the employment of hazardous substances. Textural properties, mesostructured morphology, Xray photoelectron spectroscopic and surface functional groups of products are characterized to describe synthetic mechanism. The obtained B-doped MCs show a developed mesostructure, a finite boron doping (around 2 wt %) and a high specific surface area (similar to 648.57 m(2)/g) as well as a considerable improved adsorption performance of methylene blue in a neutral aqueous solution. The product of removing boron showed the highest capture ability and the fastest absorption rate for methylene blue. The introduction of boron play important effects in the adjustments of the surface chemical properties and material structure. The method has great promising application in various fields.
