“…Here, the normalized saturation uptake, that is, saturation uptake per surface area (SUPS) was employed to evaluate the potential of functional materials (Figure 3 c). It is worth emphasizing that the record SUPS value of CH 3 -MIL-53 and OH-MIL-53 was 15.4 and 8.7 mmol m À2 , much higher than that of well-performed NU-1000 (2.1 mmol m À2 ), [14b] COF-300 (3.8 mmol m À2 ), [3] and ZIF-8 (2.8 mmol m À2 for 5-hydroxymethylfurfural), [14a] respectively.…”

Capture of high-boiling-point furfural from diluted aqueous solution is a critical but challenging step in sustainable bio-refinery processes, but conventional separation methods such as distillation and liquid-liquid extraction requires prohibitive energy consumption. We report control over the microenvironment of hydrated MIL-53 and isoreticular variants with diversified functional terephthalic acid linkers for the purpose of preferential binding of furfural through delicate host-guest interactions. Methyl-bounded MIL-53 with improved binding energy in the hydrated form results in highly efficient capture ratio (ca. 98 %) in the extremely low concentration of furfural solution (0.5-3 wt %) and 100 % furfural specificity over xylose. The distinct hydrogen bonding sites and multiple Van de Wall interactions for furfural adsorption was testified by computational modeling. Furthermore, the recovery ratio of furfural reaches ca. 93 % in desorption.

Covalent Organic Frameworks: Synthesis, Properties and Applications—An Overview

Covalent Organic Frameworks (COFs) are an exciting new class of microporous polymers with unprecedented properties in organic material chemistry. They are generally built from rigid, geometrically defined organic building blocks resulting in robust, covalently bonded crystalline networks that extend in two or three dimensions. By strategically combining monomers with specific structures and properties, synthesized COF materials can be fine-tuned and controlled at the atomic level, with unparalleled precision on intrapore chemical environment; moreover, the unusually high pore accessibility allows for easy post-synthetic pore wall modification after the COF is synthesized. Overall, COFs combine high, permanent porosity and surface area with high thermal and chemical stability, crystallinity and customizability, making them ideal candidates for a myriad of promising new solutions in a vast number of scientific fields, with widely varying applications such as gas adsorption and storage, pollutant removal, degradation and separation, advanced filtration, heterogeneous catalysis, chemical sensing, biomedical applications, energy storage and production and a vast array of optoelectronic solutions. This review attempts to give a brief insight on COF history, the overall strategies and techniques for rational COF synthesis and post-synthetic functionalization, as well as a glance at the exponentially growing field of COF research, summarizing their main properties and introducing the numerous technological and industrial state of the art applications, with noteworthy examples found in the literature.

“…Beyond toxic heavy metal and radionuclide ion capture, there are several reports on COFs as adsorbents for lanthanide ions (Nd 3+ ), [ 98 ] perrhenate (ReO 4 − ), [ 99 ] phosphorus (PO 4 3− ), [ 100 ] arsenic (AsO 4 3− ), [ 100 ] organic compounds, [ 66,67,101–104 ] and even proteins. [ 105 ] Valtchev's group reported a carboxy‐functionalized COF (3D‐COOH‐COF) through the postsynthetic modification method and applied the 3D‐COOH‐COF in selective adsorption for lanthanide ion Nd 3+ over Sr 2+ and Fe 3+ .…”

Covalent organic frameworks (COFs) are an emerging type of porous crystalline material with highly ordered aperture size and tunable structures with designer properties. COFs have been proposed as promising materials for water treatment because of their notable intrinsic properties like excellent chemostability, high surface area, abundant functional sites, and uniform adjustable aperture size. This review focuses on fundamental COF design principles for water treatment (stability, aperture size, and surface functionalization) and the state‐of‐the‐art application of COFs in desalination, organic contaminant sorption, and ion capture. Additional potential promising applications of COFs for water treatment, including solar steam generation, photocatalysis for degradation of organic contaminants, and capacitive deionization are also presented along with an outlook toward future opportunities in the field.
