The acidic ionic liquid (IL) functionalized polymer (PDVB-SO3H-[C3vim][SO3CF3]) possesses abundant nanoporous structures, strong acid strength and unique capability for deconstruction of crystalline cellulose into sugars in ILs. The polymer shows much improved catalytic activities in comparison with mineral acids, homogeneous acidic ionic liquids and the acidic resins such as Amberlyst 15. The enhanced catalytic activity found in the polymer is attributed to synergistic effects between the strongly acidic group and the ILs grafted onto the polymer, which by itself is capable of breaking down the crystalline structures of cellulose. This study may help develop cost-effective and green routes for conversion of biomass to fuels.
酸性离子液体（IL）功能化聚合物（PDVB-SO3H-[C3vim][SO3CF3]）具有丰富的纳米多孔结构、强酸强度和独特的将结晶纤维素在 ILs 中解构成糖的能力。与矿物酸、均相酸性离子液体和 Amberlyst 15 等酸性树脂相比，该聚合物显示出更高的催化活性。在聚合物中发现的增强的催化活性归因于强酸性基团和接枝到聚合物上的 IL 之间的协同作用，其本身能够破坏纤维素的结晶结构。这项研究可能有助于开发将生物质转化为燃料的经济高效和绿色途径。
