A bifunctional metal–organic framework (MOF) was successfully designed to realize the purification of 4-chlorophenol (4-CP) under simulated sunlight irradiation. Owing to the large-size mesopores of the MOF matrix NU-1000, β-CMCD (carboxylic β-cyclodextrin) could be incorporated into the frameworks with a density of 2.4% to pre-enrich the pollutant of 4-CP. Meanwhile, the photodegradation promoter [Pd(II) meso-tetra(4-carboxyphenyl)porphine] was in situ co-assembled with the organic ligand to realize its synchronous degradation. As for the current integrator, a Langmuir model was used to explain the adsorption isotherm, and the Langmuir–Hinshelwood model exhibited a better fit to its catalytic degradation behavior. Thanks to the simultaneous presence of a capturer and a photodegradation promoter, the adsorption capacity of 4-CP reached as high as 296 mg g–1, which was further completely detoxified within 60 min under simulated sunlight irradiation with a half-life time of only 5.98 min. Such excellent integrated decontamination properties prefigure the great promising potential of multifunctional MOFs in the field of pollution purification.

“…JUC-521-Fe achieved a very high catalytic activity with a reaction rate constant of 2.8 × 10 −2 /min and more than 95% degradation efficiency in just 90 min. Similar approaches have been employed by other groups to degrade pollutants such as phenol [135], BPA [136], and organic dyes [137][138][139][140][141].…”

Covalent organic frameworks (COFs) are emerging crystalline polymeric materials with highly ordered intrinsic and uniform pores. Their synthesis involves reticular chemistry, which offers the freedom of choosing building precursors from a large bank with distinct geometries and functionalities. The pore sizes of COFs, as well as their geometry and functionalities, can be pre-designed, giving them an immense opportunity in various fields. In this mini-review, we will focus on the use of COFs in the removal of environmentally hazardous metal ions and chemicals through adsorption and separation. The review will introduce basic aspects of COFs and their advantages over other purification materials. Various fabrication strategies of COFs will be introduced in relation to the separation field. Finally, the challenges of COFs and their future perspectives in this field will be briefly outlined.

“…In another study, the imine condensation between Anderson POM-linkers with -NH2 functionalities and 4-connected tetrahedral tetrakis(4-formylphenyl)silicon (TFPS) building units resulted in active POM-containing COFs (Figure 26) for selective oxidation of sulfides. [146] M-Anderson-COFs (M = Mn, Co, Fe) exhibited great catalytic activity (97-100 % conversion) for oxidizing different sulfides, even including sterically hindered substrates and with strong withdrawing groups. Moreover, no product of overoxidation was obtained with 100% sulfoxide/sulfone selectivity.…”
