摘要:

太陽能光催化分解水是實現綠色、高效生產可持續能源氫氣的重要途徑之一，而光催化劑的設計和開發在這一過程中起著關鍵作用。常用的傳統半導體光催化劑目前面臨的主要挑戰包括陽光利用率不足、載流子易復合、活性位點暴露不足等問題，因此，開發新型、高效光催化劑的研究顯得尤為重要。具有類半導體行為的金屬有機框架（metal-organic frameworks, MOFs）材料，由于其超高的比表面積、孔隙率及高規整度，近年來在光催化產氫領域受到越來越廣泛的關注。介紹了MOFs材料的結構特點及在光催化制氫領域中應用的獨特優勢，基于光催化機理從改善光吸收、促進電荷分離和加速表面反應幾個方面，總結了提高MOF基光催化劑活性的策略，并對其應用前景進行了展望。

Abstract:

Solar photocatalytic decomposition of water is one of the important ways to achieve green and efficient production of sustainable energy hydrogen, while the design and development of photocatalysts play a key role in this process. Currently, the main challenges of conventional semiconductor photocatalysts include insufficient sunlight utilization, rapid carrier recombination, and insufficient exposure of active sites. Therefore, the research on new and efficient photocatalysts is particularly important. Metal-organic frameworks (MOFs) with semiconductor-like behavior have received more and more attention in the field of photocatalytic hydrogen production in recent years due to their ultra-high specific surface area, porosity and high regularity. This article introduced the structural characteristics of MOFs materials and their unique advantages in the field of photocatalytic hydrogen production. Based on the mechanism of photocatalysis, strategies for improving the photocatalytic activity of MOF-based photocatalysts were summarized in terms of improving light absorption, promoting charge separation and accelerating surface reactions. Besides, their application prospects were prospected.
