以细菌纤维素为前驱体简便制备氮掺杂碳纤维气凝胶作为高效氧还原催化剂
摘要:数十年来, 碳气凝胶因其在催化剂载体、电容器和锂电池电极材料以及吸附剂等领域的潜在应用而备受关注. 然而, 传统碳气凝胶的制备往往使用昂贵且有毒的前驱体, 其方法也较为复杂, 不利于大规模生产及应用. 本文介绍了一种以细菌纤维素为前驱体制备氮掺杂碳纤维气凝胶的方法.该方法廉价高效, 简单易行且对环境无害. 所制气凝胶具有密度低、孔隙度高、比表面积大以及导电性良好等优点.它继承了细菌纤维素生物质优异的三维交联多孔结构的特点, 可直接用作氧还原催化剂, 表现出优异的催化性能,预示着其广泛的应用前景.这在该领域的应用报道尚属首次.Solution phase synthesis of halogenated graphene and the electrocatalytic activity for oxygen reduction reaction

碳材料催化硝基苯还原反应
摘要:本文对碳材料(主要是碳纳米管)催化硝基苯的还原反应进行了系统研究.通过热重分析、程序升温脱附、透射电子显微镜、物理吸附以及拉曼光谱等表征, 发现碳材料表面的含氧官能团在反应中起着重要的作用, 而比表面、孔结构、形貌、结构缺陷以及可能存在的铁杂质对反应没有显著影响.羰基的作用非常重要, 但是羧基和酸酐对反应不利.除此之外, 材料的π电子体系也很关键, 因为它可以传递电子, 并且利于硝基苯的吸附.硝基苯还原按照直接路径进行, 反应过程中生成的中间体亚硝基苯可以迅速转化为苯胺.
