Environmental pollution has become one of the most urgent global issues that we have to face now. Searching new technologies to solve environmental issues is of great significance. By intimately coupling photocatalytic materials with microbes, the emerging photocatalytic material–microbe hybrid (PMH) system takes advantages of the high-efficiency, broad-spectrum light capture capability of the photocatalytic material and the selectivity of microbial enzymatic catalysis to efficiently convert solar energy into chemical energy. The PMH system is originally applied for the solar-to-chemical production. Interestingly, recent studies demonstrate that this system also has great potential in treating environmental contaminations. The photogenerated electrons produced by the PMH system can reductively decompose organic pollutants with oxidative nature (e.g., refractory azo dyes) under anaerobic circumstances. Moreover, based on the redox reactions occurring on the surface of photocatalysts and the enzymatic reactions in microbes, the PMH system can convert the valences of multiple heavy metal ions into less toxic or even nontoxic status simultaneously. In this review, we introduce the recent advances of using the PMH system in treating environmental pollutions and compare this system with another similar system, the traditional intimately coupled photocatalysis and biodegradation (ICPB) system. Finally, the current challenges and future directions in this field are discussed as well.

环境污染已成为我们现在必须面对的最紧迫的全球性问题之一。寻找新技术解决环境问题具有重要意义。通过将光催化材料与微生物紧密耦合，新兴的光催化材料-微生物杂化（PMH）系统利用光催化材料的高效、广谱光捕获能力和微生物酶催化的选择性，将太阳能高效转化为化学能源。PMH系统最初应用于太阳能化工生产。有趣的是，最近的研究表明，该系统在处理环境污染方面也具有巨大潜力。PMH系统产生的光生电子可以还原分解具有氧化性的有机污染物（如 g.，耐火偶氮染料）在厌氧环境下。此外，基于光催化剂表面发生的氧化还原反应和微生物中的酶促反应，PMH系统可以同时将多种重金属离子的价态转化为毒性较小甚至无毒的状态。在这篇综述中，我们介绍了使用 PMH 系统处理环境污染的最新进展，并将该系统与另一个类似系统——传统的紧密耦合光催化和生物降解 (ICPB) 系统进行了比较。最后，还讨论了该领域当前的挑战和未来的发展方向。PMH系统可以同时将多种重金属离子的价态转化为毒性较小甚至无毒的状态。在这篇综述中，我们介绍了使用 PMH 系统处理环境污染的最新进展，并将该系统与另一个类似系统——传统的紧密耦合光催化和生物降解 (ICPB) 系统进行了比较。最后，还讨论了该领域当前的挑战和未来的发展方向。PMH系统可以同时将多种重金属离子的价态转化为毒性较小甚至无毒的状态。在这篇综述中，我们介绍了使用 PMH 系统处理环境污染的最新进展，并将该系统与另一个类似系统——传统的紧密耦合光催化和生物降解 (ICPB) 系统进行了比较。最后，还讨论了该领域当前的挑战和未来的发展方向。
