The significant reaction equipment used in the study was Perfectlight Technology's flagship product Labsolar-6A all-glass automatic online trace gas analysis system.
Highlights of the Article:
Covalent organic frameworks (COFs) are emerging crystalline porous materials formed entirely by covalent bonding of lightweight organic molecular building blocks to create two-dimensional or three-dimensional network structures. They possess excellent structural tailorability, tunable functionality, low skeletal density, high porosity, and open pore structures, making them promising in various applications such as gas storage, adsorption separation, photoelectric conversion, and multiphase catalysis. Addressing the long-standing challenge in this field of balancing "crystallinity" and "stability" in covalent assembly, the research team proposed a new concept of "Reconstructed COF (RC-COF)". This involves pre-assembling with reversible covalent bonds and then reconstructing the framework into irreversible covalent bonds to prepare highly crystalline and stable COF materials. They achieved superior carbon dioxide adsorption capacity compared to all known COF materials, as well as photocatalytic hydrogen production performance comparable to the highest-level materials in the same field. The research paper is titled "Reconstructed covalent organic frameworks", with Dr. Zhang Weiwei from East China University of Science and Technology as the first author.
