中文摘要： 基于石墨烯及其衍生物独特的化学性质，调控石墨烯基碳催化活性应用于精细化工与合成化学是功能碳材料学科的一个重要研究热点。价格低廉、资源丰富、可重复使用、易修饰、溶液可分散是石墨烯基催化材料的主要优势。催化原理不明、活性偏低、催化剂上载量过高、反应模式略有局限性是当前多数石墨烯基碳催化反应所面临的问题。本项目将在原有的工作基础上深入调控石墨烯基碳材料的化学特性、活性位点以及与其他材料的协同作用，提高石墨烯在醇氧化、碳氢键活性等重要精细化工反应催化活性；基于石墨烯碳催化活性特征进一步设计串联反应，双功能催化反应来制备附加值高的精细化工产品和复杂杂环化合物：如开发碳催化氧化与酸（碱）催化、碳催化氧化与有机小分子共催化、酸碱催化与金属催化等双功能体系；石墨烯在复合催化材料中的特殊的二维平面模板作用、共催化效果也会被探讨。研究成果将加深石墨烯在精细化工与合成化学的应用价值、丰富碳材料催化的内容和理论。

英文摘要： Graphene based carbocatalysis is emerging as an important research area. Graphene can show remarkable catalytic properties on its own and when hybridized with a second material due to its unique chemical property and 2D platform. Low cost, natural abundant, reusable, easily modification and solution processable are the main advantages. Just as every coin has two sides，it also has drawbacks in a verity of graphene based carbocatalysis such as the ambitious catalytic mechanism, relatively low reactivity, high catalyst-loading and relative poor reaction scope. In this proposal, we will continue to make efforts to develop new form of graphene based-materials with engineered morphology or functionalities, which will emerge as powerful catalysts for mediating the important synthetic transformations such as C-H oxidation and tandem alcohol oxidation to replace metal catalysts. The synergistic catalysis of carbocatalysis with metal catalysis or acid (base) catalysis or organocatalysis is another important research topic. To this end, we will design and synthesize graphene composites for cooperative catalysis for a series of synthetic transformations. The catalytic mechanism will be studied. The successful achievement of this proposal will definitely add value onto the topic of “carbocatalysis” and suggest graphene materilas can be a powerful tool for synthetic chemistry.
