Porphyrin COF and its mechanical pressing-prepared carbon fiber hybrid membrane for ratiometric detection, removal and enrichment of Cd2+

Covalent organic frameworks embedding single cadmium sites for efficient carboxylative cyclization of CO2with propargylic amines

“…In addition, due to the presence of abundant bipyridine units, the as-prepared Bpy-COF has great potential as a platform for adsorbing Cd 2+ via coordination interaction. 47 To validate this, we used Bpy-COF as an adsorbent to capture Cd 2+ (100 ppm) from an acetonitrile solution containing 83 mM DBU. Results showed that only trace amounts of Cd (94 ppb) determined by ICP analyses were detected from the filtrate after stirring for 4 h, demonstrating the significant potential of Bpy-COF as an efficient adsorbent for the removal of Cd 2+ from the solution.…”

Emerging trends in membrane-based wastewater treatment: electrospun nanofibers and reticular porous adsorbents as key components

“…Recently, a porphyrin-based COF-carbon fiber hybrid membrane was created by Jin et al using a mechanical pressing technique. 314 The porphyrin moieties showed a dual function by adsorbing Cd 2+ from water and detecting it. However, the latest developments in COF-based membranes to address heavy metal pollution are still in their infancy, and the area is anticipated to expand significantly in the years to come.…”

Plasmonic Bi/COF Nanoheterojunctions for Visible-Light Photodegradation of Phenolic Pollutants

“…As a class of highly ordered crystalline porous materials, covalent organic frameworks (COFs) have shown great promises in a variety of applications, including pollutant adsorption and separation, − proton conduction and electrical conductivity, and catalysis, due to their outstanding features of large surface area, adjustable pore size, abundant active sites, ease of functionalization, and robust chemical stability . More interestingly, COFs not only can be used as photocatalysts directly , but also may work as supports for the loading and deposition of photocatalysts or co-catalysts ( e.g.…”
