Blue light photocatalytic oxidation of sulfides to sulfoxides with oxygen over a thiazole-linked 2D covalent organic framework

Missing-linker defects in a covalent organic framework photocatalyst for highly efficient synthesis of tetrahydroquinoline

“…3D), where COF-HNU30-10 shows a smaller radius, manifesting lower charge transfer resistance. 44 Steady-state fluorescence spectroscopy and electron paramagnetic resonance spectrometry (EPR) were conducted to further verify the charge separation efficiency in the activity of COF-HNU30-10 and COF-HNU30-0. COF-HNU30-10 exhibited a lower fluorescence intensity than COF-HNU30-0 (Fig.…”

Emerging two-dimensional materials: Synthesis, physical properties, and application for catalysis in energy conversion and storage

“…The efficiency of a photoreaction relies on optical and electronic structure, physical, chemical, durability, and reusability properties. 326,327 New 2D materials are promising photocatalysts benefiting from their advantageous attributes: [328][329][330] (1) adjustable thicknesses that enable band structure tuning;…”

Reticular materials for wastewater treatment

“…The conflict between the organic linker and coordinating species at the metal core, including water or hydroxide ions, is what's responsible for the limited lifespan of MOFs. 64 The stability of isoreticular MOFs with longer linkers is worse than that of those with shorter linkers. The Pearson's HSAB principle states that soft low-valent metal ions with low charge densities can form weak coordination bonds with hard carboxylate linkers.…”
