| 摘 要： | 采用多种包覆方法制备的核壳纳米材料具有许多优于单一材料的性能，其独特的核壳结构可产生出色的协同作用和新特性，现在已经广泛用于催化、吸附、储能与转化、药物传递和光学等领域。在CO/CO2热催化加氢反应过程中，壳层包覆可对核体粒子表面进行修饰，如改变核体的表面电荷、官能团和反应特性等，从而提高核体的稳定性与分散性。核壳催化剂可形成封闭的内部微环境以富集反应物，提高反应速率和催化活性。部分核壳催化剂甚至还能实现接力催化，并提高体系内的能量利用率。主要介绍了核壳纳米材料的常用制备方法，不同类型壳层包覆的核壳催化剂在CO/CO2热催化加氢中的应用进展，并对该领域的未来发展进行了展望。

| Abstract: | The core-shell nanomaterials prepared by various coating methods have many properties that are better than those of a single material. Their unique core-shell structure can produce excellent synergistic effect and new characteristics, and have been widely used in catalysis, adsorption, energy storage and conversion, drug delivery and optics. In the process of CO/CO2 thermocatalytic hydrogenation, shell coating can modify the surface of core particles, such as changing the surface charge, functional groups and reaction characteristics of the core, so as to improve the stability and dispersion of the core. Core-shell catalysts can form a closed internal microenvironment to enrich reactants, improve reaction rate and catalytic activity. Some core-shell catalysts can even realize relay catalysis and improve energy utilization in the system. The common preparation methods of core-shell nanomaterials and the application progress of core-shell catalysts coated with different types of shells in CO/CO2 thermocatalytic hydrogenation were mainly introduced, and the future development in this field was prospected. |
