Finding advanced technologies to store solar energy in chemical bonds efficiently is of great significance for the sustainable development of our society. The recently reported photocatalyst-microbe hybrid (PMH) system couples photocatalysts intimately with microbes and endows heterotrophic microbes with light-harvesting capacity. Generally, when PMH systems are exposed to light, photocatalytic reactions occur on the surface of photocatalysts and the photogenerated electrons enter microbial cells to promote the generation of energy carriers (such as nicotinamide adenine dinucleotide phosphate hydrogen and adenosine triphosphate) and the following chemical synthesis. PMH system applications have expanded from synthesizing value-added products (chemicals, fuels, and polymers) to treating pollutants. However, the successful operation of the PMH system relies on the timely eradication of the photogenerated holes as they recombine with the photogenerated electrons and cause the photocorrosion of the photocatalyst. This review summarizes the strategies for scavenging the photogenerated holes in PMH systems and provides insight into the current gaps and outlooks for future opportunities in this field.
寻找能将太阳能高效存储于化学键中的先进技术，对我们社会的可持续发展具有重大意义。最近报道的光催化剂-微生物混合（PMH）系统将光催化剂与微生物紧密结合，赋予异养微生物光捕获能力。一般来说，当PMH系统暴露于光下时，光催化反应在光催化剂表面发生，光生电子进入微生物细胞以促进能量载体（如还原型辅酶Ⅱ和三磷酸腺苷）的生成以及后续的化学合成。PMH系统的应用已从合成增值产品（化学品、燃料和聚合物）扩展到处理污染物。然而，PMH系统的成功运行依赖于及时消除光生空穴，因为它们会与光生电子复合并导致光催化剂的光腐蚀。本综述总结了PMH系统中清除光生空穴的策略，并深入探讨了该领域当前的差距以及未来机会的展望。
