摘要

随着能源危机和温室效应的加剧,开发新型光催化系统以高效地生产太阳能燃料/化学品具有重要的现实意义和科学意义。在这种情况下,单原子光催化(SAP)系统由于其优越的催化效率、大表面积和高原子利用率而被认为是多相光催化发展的重大突破。sap是由孤立的单原子(SAs)组成的,它们分布在/或与合适载体的表面原子配位。将SAs锚定在二维基底上,使所开发的sap具有优异的性能,包括高负载、均匀配位、高光收集能力和光催化活性增强。最近,许多2D衬底,包括碳材料、MXenes和过渡金属硫族化合物,已被用于锚定金属sa,用于不同的光催化应用。本文系统地讨论了SAPs和金属SAs在二维支架上的限制。此外,本文还重点介绍了SAPs用于能量转换的最新进展、存在的挑战和未来的展望。我们希望本文的综述能够为未来发现新的光催化体系提供一些思路。

Metal single atom doped 2D materials for photocatalysis: current status and future perspectives
With the increase of energy crisis and greenhouse effect, the development of new photocatalytic systems with efficient solar-driven fuels/chemicals production is of great practical and scientific importance. In this scenario, single atom photocatalytic (SAP) systems are considered a significant breakthrough in the development of heterogeneous photocatalysis due to their superior catalytic efficiency, large surface area, and high atomic utilization. SAPs are consisting of isolated single atoms (SAs) distributed on/or coordinated with surface atoms of a suitable support. The anchoring of SAs on 2D substrates endows the developed SAPs with excellent properties, including high loading, uniform coordination, high light harvesting capability, and enhanced photocatalytic activities. Recently, many 2D substrates, including carbon materials, MXenes, and transition metal chalcogenides, have been used to anchor metal SAs for different photocatalytic applications. This review systematically discusses SAPs and the confining of metal SAs on 2D supports. Moreover, this review highlights the recent advances of SAPs for energy conversion, the existing challenges, and future perspectives. We expect that this review will offer some ideas for the future discovery of novel photocatalytic systems.

期刊介绍: Progress in Energy and Combustion Science (PECS) publishes review articles covering all aspects of energy and combustion science. These articles offer a comprehensive, in-depth overview, evaluation, and discussion of specific topics. Given the importance of climate change and energy conservation, efficient combustion of fossil fuels and the development of sustainable energy systems are emphasized. Environmental protection requires limiting pollutants, including greenhouse gases, emitted from combustion and other energy-intensive systems. Additionally, combustion plays a vital role in process technology and materials science. PECS features articles authored by internationally recognized experts in combustion, flames, fuel science and technology, and sustainable energy solutions. Each volume includes specially commissioned review articles providing orderly and concise surveys and scientific discussions on various aspects of combustion and energy. While not overly lengthy, these articles allow authors to thoroughly and comprehensively explore their subjects. They serve as valuable resources for researchers seeking knowledge beyond their own fields and for students and engineers in government and industrial research seeking comprehensive reviews and practical solutions.
