“…The IR spectrum of MIL-88B shows a characteristic peak at 543 cm –1 , which is attributed to the bending vibration of Fe–O. The absorption peaks at 1591 and 1388 cm –1 originate from the asymmetric and symmetric stretching vibration modes of the carboxyl groups, indicating the presence of dicarboxylate ligands in the as-obtained MOF . The vibrational bands at 1504 and 749 cm –1 are ascribed to the CC stretching and C–H bending vibrations of the aromatic ring .…”

In this work, a metal−organic framework with an octahedral morphology supported by a tungstosilicic acid (TSA) nanocatalyst has been successfully synthesized through a postsynthetic modification approach and referred to as TSA/MIL-88B. The as-prepared catalyst was efficiently obtained from Biginelli reactions among benzaldehyde, urea, and 1,3-dicarbonyl compound. Depending on the synergistic effect of exposed metal iron sites and the supported Brønsted acid sites, the hybrid materials exhibited high catalytic activity. Additionally, the environmentally friendly nanocatalyst could be recycled seven times with a little reduction in the catalytic performance. This study also provides a way for the application of such porous organic polymer functionalization in organic synthesis.

“…Later, the group reported a bio-assisted 2D/2D TiO 2 /MIL-88(Fe) (TCS@MOF) heterojunction as a photocatalyst for monocrotophos (MCP) degradation. [120] The catalyst achieved a significant catalytic activity of 98.79% for the degradation of MCP within 30 min under visible light irradiation and maintain a stability after 5 cycles for the oxidation of MCP.…”

Water quality can have serious impacts on human health. One crucial issue of water pollution seriously affects our safety due to the continually emerging of discovered anthropogenic pollutants. The water treatment technologies are persistent improvement to adapt such new contaminants, which accelerates the evolution of materials science to explore solving the problems. Metal-organic Frameworks (MOFs) as the significant porous and multi-dimensional networks has been concerned for toxic pollutant elimination, especially probed the applications of outstanding layered 2D skeletons MOFs-based materials. The emphases of this review highlight the 2D MOFs-based materials used in water remediation and treatment strategies including adsorption and catalysis methods. Further, the prospects and challenges of 2D MOFs-based materials for water treatments applications would be surveyed meticulously for the future research and development.

“…136 As the initial concentration increases, the degradation rate of pollutants will also decrease. Wang et al 136 studied the photocatalytic degradation of a series of concentrations (10,20,30,40, and 50 mg L −1 ) of tetracycline and found that the removal rate decreased from 88.3% to 66.0%. This phenomenon can be attributed to the following reasons: on the one hand, the increase in antibiotic concentration causes photons to quickly enter the antibiotic solution.…”

“…At present, there are many interesting studies on the photocatalytic degradation of pollutants in water based on MOFs. For example, Sivakumar Vigneshwaran et al 20 designed a TCS@MOF heterojunction and applied it for the degradation of monocrotophos under visible light irradiation. Importantly, because the heterojunction formed a fast transfer carrier channel, the electron hole pairs were rapidly separated and the degradation rate reached 98.79% within 30 min.…”
