Continuous industrialization has raised daunting environmental concerns, and there is an urgent need to develop a sustainable strategy to tackle the contamination issues. Here, we report a supramolecular photoenzyme ensemble enabling the harvest of solar energy to remove contaminations in water. The well-sourced oxidoreductase, laccase, is confined into a photoactive hydrogen-bonded organic framework (PHOF) through an in situ encapsulation method. The direct electron migration between the oxidation center in a PHOF and the reduction center in laccase facilitates synergistic photoenzyme-coupled catalysis, showing two orders of magnitude higher activity than free laccase for pollutant degradation under visible light, without the need for sacrificial agents or costly co-mediators. Such high decontamination efficiency also surpasses the reported catalysts. The structure and decontamination function of this supramolecular photoenzyme ensemble remain highly stable in complex environment matrices, presenting desirable reusability and almost 100% conversion efficiency of pollutants for real sewage samples. Our conceptual photoenzyme hybrid catalyst offers important insights into green and sustainable water decontamination.

使用超分子光酶集成提高光催化净化效率


持续的工业化引发了令人生畏的环境问题，迫切需要制定可持续的战略来解决污染问题。在这里，我们报道了一个超分子光酶系综，能够收集太阳能以去除水中的污染物。来源良好的氧化还原酶漆酶通过原位封装方法被限制在光活性氢键有机框架 （PHOF） 中。PHOF 中的氧化中心和漆酶中的还原中心之间的直接电子迁移促进了协同光酶耦合催化，在可见光下显示出比游离漆酶高两个数量级的污染物降解活性，而无需牺牲剂或昂贵的共介质。如此高的净化效率也超过了已报道的催化剂。这种超分子光酶集合的结构和去污功能在复杂环境基质中保持高度稳定，为真实污水样品提供理想的可重用性和几乎 100% 的污染物转化效率。我们的概念性光酶杂化催化剂为绿色和可持续水净化提供了重要的见解。
