Efficient capture of solar energy will be critical to meeting the energy needs of the future. Semiconductor photocatalysis is expected to make an important contribution in this regard, delivering both energy carriers (especially H ) and valuable chemical feedstocks under direct sunlight. Over the past few years, carbon dots (CDs) have emerged as a promising new class of metal-free photocatalyst, displaying semiconductor-like photoelectric properties and showing excellent performance in a wide variety of photoelectrochemical and photocatalytic applications owing to their ease of synthesis, unique structure, adjustable composition, ease of surface functionalization, outstanding electron-transfer efficiency and tunable light-harvesting range (from deep UV to the near-infrared). Here, recent advances in the rational design of CDs-based photocatalysts are highlighted and their applications in photocatalytic environmental remediation, water splitting into hydrogen, CO reduction, and organic synthesis are discussed.
高效捕获太阳能对于满足未来的能源需求至关重要。半导体光催化有望在这方面做出重要贡献，在阳光直射下提供能量载体（特别是 H ）和有价值的化学原料。在过去的几年中，碳点（CDs）作为一种很有前途的新型无金属光催化剂出现，由于其易于合成、独特的结构、可调的组成、易于表面功能化、出色的电子转移效率和可调谐的光捕获范围（从深紫外到近红外），表现出半导体光电特性，并在各种光电化学和光催化应用中表现出优异的性能。本文重点介绍了基于 CDs 的光催化剂的合理设计方面的最新进展，并讨论了它们在光催化环境修复、水分解为氢气、CO 还原和有机合成中的应用。
