Metal–Organic Frameworks for Photocatalysis and Photothermal Catalysis

Accounts of Chemical Research, Год журнала: 2018, Номер 52(2), С. 356 - 366

Опубликована: Дек. 20, 2018

To meet the ever-increasing global demand for energy, conversion of solar energy to chemical/thermal is very promising. Light-mediated catalysis, including photocatalysis (organic transformations, water splitting, CO2 reduction, etc.) and photothermal catalysis play key roles in via light-matter interaction. The major challenges traditional semiconductor photocatalysts include insufficient sunlight utilization, charge carrier recombination, limited exposure active sites, particularly difficulty understanding structure-activity relationship. Metal-organic frameworks (MOFs), featuring semiconductor-like behavior, have recently captured broad interest toward because their well-defined tailorable porous structures, high surface areas, etc. These advantages are beneficial rational structural modulation improved light harvesting separation as well other effects, greatly helping address aforementioned especially facilitating establishment Therefore, it increasingly important summarize this research field provide in-depth insight into MOF-based accelerate future development. In Account, we summarized recent advances these two directly relevant applications, mainly focusing on results our lab. Given unique features MOFs, put an emphasis material design optimize components performance understand related mechanisms behind enhanced activity. This Account starts by presenting overview catalysis. We explain why MOFs can be promising exemplify behavior MOFs. More importantly, show that a powerful platform study photocatalysis, which involved three processes, namely, harvesting, electron-hole separation, redox reactions, rationally improved. Meanwhile, relationship dynamics illustrated part. addition, been introduced based effect plasmonic metals and/or together with light-driven electronic state optimization heterogeneous organic reactions. Finally, brief outlooks current development MOF provided. It believed will afford significant inspirations over catalysts.

Metal–organic frameworks (MOFs) have been used for photodynamic therapy (PDT) of cancers by integrating photosensitizers, which cause cytotoxic effects on cancer cells converting tumor oxygen into reactive singlet (1O2). However, the PDT efficiency MOFs is severely limited hypoxia. Herein, decorating platinum nanozymes photosensitizer integrated MOFs, we report a simple yet versatile strategy enhanced PDT. The nanoparticles homogeneously immobilized possess high stability and catalase-like activity. Thus, our nanoplatform can facilitate formation 1O2 in hypoxic site via H2O2-activated evolvement O2, more serious damage to cells. Our finding highlights that composites potential serve as efficient agents therapy, will open an avenue toward biological applications.
