Solar fuels and chemical production using photosynthetic devices by harnessing solar energy remains an attractive prospect owing to its being a potential alternative to fossil feedstocks, though such artificial photosynthetic systems for direct solar-to-chemical conversion are still far from industrial applications as a consequence of emergent challenges that may be well addressed by the exploration of integrated photocatalysis devices with enhanced activity, selectivity, and stability. Simultaneously embedding dual cocatalysts onto photocatalysts aims to tackle these limitations of artificial photosynthesis initiated by the bare photocatalyst while offering an opportunity to realize their synergistic operations. In this review, we summarize the essential design principles and emerging configurations of dual cocatalysts, and provide a side-by-side comparison to reveal their strengths and deficiencies. In parallel, we discuss how to choose a pair of redox cocatalysts for a specific photocatalytic redox reaction, and how some key lessons that have emerged from the relevant studies can be applied into further investigations for fuels and chemicals generation. Finally, we outline the remaining challenges and potential advances in the discovery of a robust and renewable artificial photosynthesis system.

用于人工光合作用的氧化还原助催化剂的整合

通过利用太阳能利用光合作用装置生产太阳能燃料和化学品仍然是一个有吸引力的前景，因为它是化石原料的潜在替代品，尽管这种用于直接太阳能到化学转化的人工光合作用系统仍然远离工业应用，因为通过探索具有增强活性、选择性和稳定性的集成光催化装置，可以很好地解决新出现的挑战。同时将双助催化剂嵌入光催化剂上旨在解决由裸光催化剂引发的人工光合作用的这些局限性，同时提供实现它们协同操作的机会。在这篇综述中，我们总结了双助催化剂的基本设计原则和新兴构型，并提供并排比较以揭示他们的优势和不足。同时，我们讨论了如何为特定的光催化氧化还原反应选择一对氧化还原助催化剂，以及如何将相关研究中出现的一些关键经验应用于燃料和化学品生成的进一步研究。最后，我们概述了发现强大且可再生的人工光合作用系统方面的剩余挑战和潜在进展。
