地球上的能量主要来源于太阳光辐射,绿色植物及微生物通过光合作用吸收光能,经过光电催化过程和多酶催化过程,将CO_2转化为碳水化合物.基于仿生思想,模拟光合作用中酶光协同催化过程,构建酶光耦合系统,利用酶催化过程进行CO_2转化,利用光催化过程提供能量及电子,协调优化酶催化和光催化过程,实现CO_2高效绿色转化,可有效调节因化石燃料过度使用引起的碳循环失衡.酶光耦合催化系统构建过程简便,催化产物种类可控,为生物催化在化工、能源、环境等领域的应用提供了范例.本文从单酶催化和多酶催化角度分别介绍了两类酶催化系统转化CO_2的研究现状,从电子传递角度介绍了辅酶依赖型和辅酶非依赖型酶光耦合催化系统的研究进展.最后,对本领域发展现状和趋势进行了简要总结和展望.
The energy of the earth mainly comes from solar radiation, and the green plants and microorganisms absorb light energy through photosynthesis, and convert CO 2 into carbohydrates through photoelectrocatalytic process and multi-enzyme catalysis process. Based on the bionics idea, Catalyzed process, the enzyme coupling system is constructed, the CO 2 transformation is performed by the enzyme catalysis process, the energy and the electron are provided by the photocatalysis process, the enzyme catalysis and the photocatalysis process are coordinated and optimized to realize the high-efficiency green conversion of CO 2, and the effective regulation of fossil fuel overuse The carbon cycle imbalance.The construction of enzyme-optical coupling catalytic system is simple and the types of catalytic products are controllable, which provides an example for the application of biocatalysis in the fields of chemical industry, energy and environment.In this paper, Class enzyme catalytic system into CO 2, and the research progress of coenzyme-dependent and coenzyme-independent enzyme photo-coupled catalytic system is introduced from the viewpoint of electron transfer.Finally, the status and trend of development in this field are briefly summarized and prospected.
