“…[17,18] Here, we demonstrate the incorporation of a metal-organic framework (MOF) as well as a calcined product of the MOF to modify surface-active sites of TiO 2 for a better photocatalytic activity. [21][22][23][24][25] MIL-53(Fe), in particular, is a promising MOF for the removal of organic pollutants due to its good absorption property as well as responses to the UV-Vis region, which are at a lower bandgap energy (2.88 eV). [19,20] To date, MOFs have displayed various properties, for instance gas adsorption, adsorption of organic and inorganic pollutants, sensing, separations, catalysis, photocatalysis, and drug delivery.…”

Photocatalytic activity of titanium(IV) oxide (TiO2) can be enhanced through modification of its surface‐active sites. Here, iron(III) carboxylate [MIL‐53[Fe]]‐incorporated TiO2 (as MIL‐53(Fe)/TiO2) was prepared using a hydrothermal method. This material was then calcined at 500°C to obtain a MIL‐53(Fe)‐derived γ‐Fe2O3/TiO2 photocatalyst. A photocatalytic study of MIL‐53(Fe)/TiO2 and MIL‐53(Fe)‐derived γ‐Fe2O3/TiO2 toward cationic methylene blue (MB) and anionic methyl orange (MO) showed that MIL‐53(Fe)/TiO2 (0.25 wt%) and MIL‐53(Fe)‐derived γ‐Fe2O3/TiO2 (0.75 wt%) resulted the best degree of dye degradation. The MIL‐53(Fe)‐derived γ‐Fe2O3/TiO2 (0.75 wt%) composite for instance is capable of degrading almost 100% of 20‐ppm MB and MO, respectively, within 6 hr. Photocatalytic degradation of MB and MO was well fitted to the Langmuir‐Hinshelwood pseudo‐first order kinetics model, which indicates physisorption as the key partway that facilitates dye decomposition on the surface of a photocatalyst under UV‐A irradiation. This study provides new insights into the exploration of MILs/TiO2 materials for the environmental remediation and pollution control.

“…Metal-organic frameworks (MOFs) form a class of porous materials that have been intensively studied in the last decade [1][2][3][4][5][6]. MOFs provide diverse and easily modifiable architectures and topologies and play important roles in synthetic chemistry [7], catalysis [2,[8][9][10], molecular separation [11], magnetism [12,13], optics [14,15] possess luminescence [16,17], and are used as potential drug delivery carriers [18][19][20].…”

“…Herein, we report on the synthesis and characterization of a series of lanthanide-based MOFs of general formula [LnL(H 2 O) 2 ] n where Ln = La (1), Ce (2), Nd (3), Eu (4), Gd (5), Dy (6), and Ho (7), and 1,3,5-tris(4-carboxyphenyl)-2,4,6-trimethylbenzene (H 3 L) is the linker. The aim of this work was the synthesis of new MOFs with the tribasic tricarboxylate H 3 L ligand (MTBA) and the investigation of their physicochemical properties, crystal structures, thermal, and luminescence properties.…”

New metal-organic frameworks (MOF) with lanthanum(III), cerium(III), neodymium(III), europium(III), gadolinium(III), dysprosium(III), and holmium(III)] and the ligand precursor 1,3,5-tris(4-carboxyphenyl)-2,4,6-trimethylbenzene (H3L) were synthesized under solvothermal conditions. Single crystal x-ray analysis confirmed the formation of three-dimensional frameworks of [LnL(H2O)2]n·xDMF·yH2O for Ln = La, Ce, and Nd. From the nitrogen sorption experiments, the compounds showed permanent porosity with Brunauer-Emmett-Teller (BET) surface areas of about 400 m2/g, and thermal stability up to 500 °C. Further investigations showed that these Ln-MOFs exhibit catalytic activity, paving the way for potential applications within the field of catalysis.

“…Metal organic frameworks (MOFs) are porous solids whose physico-chemical properties can be extensively modified due to perpetual possibilities in varying two components constituting their structure i.e. the inorganic metal nodes and/or the organic ligands [1][2][3][4][5]. This tunable nature of the MOFs have been exploited in numerous applications such as gas storage, energy storage, water adsorption, catalysis, membranes etc… [4,6].…”

Though Metal Organic Frameworks (MOF's) and MOF-derived solids have been employed in various applications, especially catalysis, there is still a constant search for better performing MOF-based hybrid catalysts. In this work, we employed sacrificial template method in synthesizing MIL-53(Al) type-porous Alumina (MA) composites that exhibit different physico-chemical and catalytic properties compared to parent solids (MIL-53 and mesoporous Al 2 O 3). Structural investigations demonstrated that composites possess combined structure of both the parent solids. Novel composites possess hierarchical (meso-& micro-) pores, with average pore width in the range of ~14 to 16 nm. NH 3 adsorption calorimetry and isopropanol test enabled deducting the possible nature and strength of acid-basic sites in composites. 'MA' composites show intermediate chemical properties and synergistic multifunctional catalytic behavior compared to parent solids. This work reveals, for the first time, extensively tunable physico-chemical properties of a novel class of solids: "the MIL-53(Al) type-porous alumina composites" that can have a huge potential as multifunctional catalysts.
