Artificial photosynthesis is the mimicry of the natural process of solar energy conversion into chemical energy carriers. Photocatalytic systems that combine light-harvesting materials and catalysts in solution or suspension provide a promising route towards this goal. A key requirement for a sustainable solar fuel production system is a low-cost, stable and non-toxic light harvester. Photoluminescent carbon nanoparticles, carbon dots (CDs), are promising emerging light-harvesters for photocatalytic fuel production systems. CDs possess many desirable properties for this purpose, such as inexpensive, scalable synthetic routes, low-toxicity and tuneable surface chemistry. In this tutorial review, the integration of CDs in photocatalytic fuel generation systems with metallic, molecular and enzymatic catalysts is discussed. An overview of CD types, synthesis and properties is given along with a discussion of tuneable CD properties that can be optimised for applications in photocatalysis. Current understanding of the photophysical electron transfer processes present in CD photocatalytic systems is outlined and various avenues for their further development are highlighted.

碳点作为光敏剂用于太阳能驱动的催化

人工光合作用是模仿太阳能转化为化学能载体的自然过程。将光收集材料和催化剂混合在溶液或悬浮液中的光催化系统为实现该目标提供了有希望的途径。可持续的太阳能生产系统的关键要求是低成本，稳定且无毒的光收集器。光致发光的碳纳米颗粒，即碳点（CD），是用于光催化燃料生产系统的有前途的新兴光收集器。CD具有许多用于此目的的理想特性，例如廉价，可扩展的合成路线，低毒性和可调节的表面化学性质。在本教程的复习中，讨论了将CD与金属，分子和酶促催化剂在光催化燃料生成系统中的集成。CD类型概述给出了合成和特性，并讨论了可优化的CD特性，该特性可针对光催化应用进行优化。概述了目前对CD光催化系统中光物理电子转移过程的理解，并着重指出了其进一步发展的各种途径。
