Sorption and photodegradation under visible light irradiation of an organic pollutant by a heterogeneous UiO-67–Ru–Ti MOF obtained by post-synthetic exchange

Abstract

By exchanging metals in a photoactive MOF, it has been possible to obtain a material for the photodegradation of methylene blue.

Long‐Term Photostability in Terephthalate Metal–Organic Frameworks

“…Due to a combination of positive features including flexibility in the design, wide selection of metals and organic linkers, possibility to incorporate co‐catalysts and large surface area, metal–organic frameworks (MOFs) are currently attracting considerable attention as photocatalysts to perform degradation of organic pollutants and for production of solar fuels …”

Metal–organic framework sorbents for the removal of perfluorinated compounds in an aqueous environment

“…[11] Zirconium-MOFs, UiO-66 and 67 built with bdc (benzene-dicarboxylic acid) and bpdc (biphenyl-dicarboxylic acid) ligands respectively, have shown to possess very high thermal, chemical and water stability, [12] making them suitable as sorbents for environmental purposes. [13,14] Recently, we have shown that Zirconium-MOF UiO-66, with small cavity, can efficiently adsorb PFOX. [15] In this study, we evaluated the efficiency of UiO-67, with larger cavity, for the removal of PFOX in aqueous solution.…”

Photo-Catalytic Behavior of Cdse QDS Sensitized Zr-(1,3,5-Benzene Tricarboxylic Acid) Metal-Organic Frameworks.

“…If a MOF is employed as light-sensitive semiconductor, the central metal-oxide cluster can be considered as a discrete QD, which is stabilized and interconnected by the organic linkers acting as photon antenna [26]. Compared with traditional semiconductor photo-catalysts, the superiority of MOFs originates from their ultrahigh surface area and narrow micropore distribution, which may lead to the formation of mono-disperse photoactive species supported on MOFs [27][28]. However, the photo-activity of MOF was not as effective as that of inorganic semiconductor NPs.…”
