摘　　要：介绍了核壳结构材料的组成及其在催化反应中的作用,分析和讨论了核壳结构催化剂在二氧化碳加氢制备烷烃、低碳烯烃、醇类、二甲醚及芳烃中的功能及作用原理:核壳结构提供了更大的反应空间,能增大反应物与催化剂的接触效率,有效控制有毒物质的进入,延长催化剂寿命。合成比例、壳层厚度、活性物质的选择以及制备方法的不同会直接影响二氧化碳的转化率和反应产物的分布,同时指出了制备成本低、可回收、高效且耐腐蚀的核壳催化剂是二氧化碳加氢反应研究的发展趋势。The composition of core-shell structure material and its role in catalytic reaction are introduced.The function and principle of core-shell catalysts in the hydrogenation of carbon dioxide to alkanes, light alkenes, alcohols, dimethyl ethers and aromatics are analyzed and discussed.The core-shell structure can provide a larger reaction space, increase the contacting efficiency between reactants and catalyst, effectively control the entry of toxic substances, and prolong the catalyst life.The ratio of synthesis, the thickness of shell, the selection of active substances and the different preparation methods can directly affect the conversion rate of carbon dioxide and the distribution of reaction products. Meanwhile, it is pointed out that the preparation of core-shell catalyst with low cost, recyclable, high efficiency and corrosion resistance is the research and development trend of carbon dioxide hydrogenation.
