    摘要:

    半导体材料与氧化还原类酶的杂化体系已成为近年来研究的热点,为工业生产、环境治理等领域提供了全新的思路与方向。本文从半导体的选择、杂化系统中酶的应用、牺牲剂的种类3个方面系统地介绍了组成杂化系统的各种组分,总结分析各个组分的特点和在系统中的作用。并以“半导体-固氮酶”、“半导体-氢化酶”、“半导体-CO2还原酶\CO脱氢酶”3种杂化系统为例,介绍了不同杂化系统组成和反应特点。简要地描述了杂化系统的工作过程与“牺牲剂-半导体-酶”直接途径、“牺牲剂-半导体-介体-酶”间接途径两种不同的电子传递途径,指出了现有研究在半导体材料毒性、电子利用效率等方面的局限,并提出该系统在仿生细胞器研究、优化反应链等方向上的前景与展望。

    Abstract:

    The hybrid systems of semiconductor materials and oxidation-reduction enzymes have become a research hotpot in recent years, providing new ideas and directions for industrial production, environmental management and other fields. In this paper, we systematically introduce the hybrid system of semiconductors and oxidation-reduction enzymes in three aspects: the selection of semiconductors, the application of enzymes in the system and the types of sacrificial agents. Moreover, the characteristics and the uses of each component are also summarized and analyzed in this paper. We also introduce the compositions and reaction characteristics of different hybrid systems, by taking “semiconductor-nitrogenase” hybrid system, “semiconductor-hydrogenase” hybrid system and “semiconductor-CO2 reductase /CO dehydrogenase” hybrid system as examples. Besides, we briefly describe the working process and two different electron transfer pathways of the hybrid system, the direct pathway of “sacrificial agent-semiconductor-enzyme” and indirect pathway of “sacrificial agent-semiconductor-intermedia-enzyme” Finally, we summarize some limitations in the past research, such as the toxicity of semiconductor materials and the low electronic utilization efficiency, we propose new prospects and research directions in bionic organelle and optimization of the reaction chain.
