Three-dimensional covalent organic framework with tty topology for enhanced photocatalytic hydrogen peroxide production

Miaomiao Wu et al.

Summary: In this study, a novel 8-connected cubic node, octa-aldehyde difluorobenzene monomer, was designed and synthesized for the first time to construct a 3D COF (COF-NUST-16) with the tty topology using a [8 + 4] reticular strategy. The resulting 8-connectivity 3D COF exhibited high photocatalytic activity for the production of hydrogen peroxide, with a production rate 4 times higher than a 2D COF of similar chemical structure. This work not only enriches the topological diversity of COFs, but also opens up new possibilities for the application exploration of 3D COFs.

A Crystalline Partially Fluorinated Triazine Covalent Organic Framework for Efficient Photosynthesis of Hydrogen Peroxide

Haozhen Wang et al.

Summary: The TF50-COF catalyst, a partially fluorinated, metal-free, imine-linked two-dimensional triazine covalent organic framework, demonstrates high selectivity and stability in O-2 photoreduction into H2O2. By varying the proportion of fluorine substitution, the catalyst maximizes interlayer interactions, improves crystallinity, accelerates carrier transfer, and enhances photostability. The catalyst achieves a high H2O2 yield rate of 1739 mu mol h(-1) g(-1) and an apparent quantum efficiency of 5.1 % at 400 nm, surpassing the performance of previously reported nonmetal COF-based photocatalysts.

Constructing Synergistic Triazine and Acetylene Cores in Fully Conjugated Covalent Organic Frameworks for Cascade Photocatalytic H2O2 Production

Lipeng Zhai et al.

Summary: Covalent organic frameworks (COFs) are a suitable template for photocatalytic H2O2 synthesis due to their tunable chemical structures and semiconductor properties. However, the photoactivity of COFs is still suboptimal due to inefficient charge generation, fast recombination of photogenerated charges, and limited electron transport. In this study, triazine and acetylene units were integrated into COFs, leading to efficient charge separation, suppressed charge recombination, and enhanced electron transport. Experimental and computational results demonstrated that triazine and acetylene units synergistically promoted H2O2 synthesis through a two-electron pathway.
