摘要果糖是一种重要的食品饮料原料，也是生产生化产品的可再生资源。本文制备了一系列N掺杂介孔碳材料（MCNs），并对其作为催化葡萄糖异构化成果糖的多相催化剂进行了评价。以对苯二胺二磺酸为原料，通过炭化法制备了mcn，考察了氢氧化钠脱硫和加氢处理对mcn的影响。发现H2SO4/pPDA的摩尔比对多孔结构和含氮量有重要影响。NaOH处理下的脱硫处理可以很大程度上消除碳边的磺酸基，从而提高MCN材料的碱性，而氢化还原可以修饰N原子种类，增强碱性位点的强度，从而提高葡萄糖异构化成果糖的催化活性。在所有制备的MCN样品中，MCN-2- dh在水溶液中表现出良好的活性，其果糖收率为31.6%，选择性为84.6%。图形抽象
AbstractFructose is not only an important food and beverage ingredient, but also a renewable resource for production of bio-chemicals. In this paper, a series of N doped mesoporous carbon materials (MCNs) were prepared and evaluated as heterogeneous catalysts for catalytic isomerization of glucose to fructose. The MCNs were prepared through carbonization ofp-phenylenediamine disulfate and the effects of desulfonation with NaOH and hydrogenation treatments were examined. It is found that the molar ratio of H2SO4/pPDA crucially affects the porous structure and the nitrogen content. Desulfonation with NaOH treatment could largely eliminate the sulfonic groups on the carbon edges and thus enhance the basicity of the MCN materials, whereas hydrogenation reduction could modify the N atom species and reinforce the strength of the basic sites, as a result enhancing the catalytic activities in glucose isomerization to fructose. Among all of the prepared MCN samples, MCN-2-DH showed an excellent activity in aqueous solution, which afforded a fructose yield of 31.6% with 84.6% selectivity.Graphic Abstract
