Metal-organic frameworks (MOFs) have attracted more attention and research in the field of photocatalysis due to their diverse topology, highly ordered and tunable pore structures, high specific surface area, widely distributed active sites, short photo-generated carrier diffusion distance, and good photo-thermal stability. However, MOFs photocatalytic materials have wide bandgap structures and high charge transfer resistance, which still face problems such as difficult photo-generated charge separation and low quantum efficiency in the field of photocatalysis. Professor Yongfa Zhu from Tsinghua University and Associate Professor Haibing Meng from Taiyuan University of Technology have embedded C₆₀ into zirconium-based MOFs with pore size matching, constructing a novel host-guest MOFs photocatalyst. The material has a strong built-in electric field and highly ordered crystal structure, which promotes the separation and migration of photo-generated charges and achieves efficient photocatalytic hydrogen production. The related results were published in Angew. Chem. (DOI: 10.1002/anie.202217897).
