In2S3/In2O3 composites were fabricated by annealing using metal-organic framework (In-MOF) as precursor, following by sulfurization of In2O3. Structural characterization showed that two kinds of In2S3/In2O3 with different morphologies were obtained by controlling the pH condition during the sulfurization process. Optical characterization results revealed that In2S3/In2O3 heterojunctions display an evidently decreased visible light emission and enhanced visible light absorption compared with that of pure In2O3. The In2S3/In2O3 heterojunction exhibited improved visible-light photocatalytic activities, the optimal composite (pH=2) showed the highest efficiency of 91.14%. The improvement of photocatalytic performance was attributed to the construction of heterojunction.

The first mesoporous bimetallic TiIII/Al metal-organic framework (MOF) containing amine functionalities on its linkers has been selectively obtained by converting the cheap commercially available (TiCl3)3AlCl3 into Ti3-xAlxCl3(THF)3 and reacting this complex with 2-aminoterephthalic acid in DMF under soft solvothermal conditions. This compound is structurally related to the previously described NH2-MIL-101(M) (M = Cr, Al and Fe) MOFs. Thermal gravimetric analyses and in situ PXRD measurements demonstrated that this highly air-sensitive TiIII-containing MOF is structurally stable up to 200°C. Nuclear magnetic resonance (NMR) spectroscopy, elemental and inductively-coupled plasma (ICP) analyses revealed that NH2-MIL-101(TiIII) contains trinuclear Ti3(μ3-O)Cl(DMF)2(RCOO)6 clusters with strongly bound DMF molecules, and a small amount of aluminum. Sorption experiments reveal a higher affinity of this MOF for hydrogen compared to the previously described monometallic unfunctionalized MIL-101(TiIII) MOF.

UiO-66 is a zirconium-based metal organic framework (MOF). It was synthesized and used by researchers due to its high water, chemical and thermal stability. The mentioned reasons in addition to other excellent properties made them a highly competitive materials for a variety of industrial problems. This study investigates the effect of the reaction time on the characteristics of the prepared UiO-66 nanoparticles. UiO-66 was synthesized by the solvothermal method and the reaction was left to take place for 18, 21 and 24 hours. UiO-66 was characterized using X-ray Diffraction (XRD) and Fourier-Transform Infrared (FTIR), the results showed that it has the same patterns and functional groups of the previously reported UiO-66. In addition, Scanning Electron Microscopy (SEM) was used to confirm the morphology of UiO-66. The smallest particle size around 200 nm was obtained at 18 hours. To investigate the thermal stability of the prepared UiO-66, Thermogravimetry analysis (TGA) was conducted. The results matched well with the literature and confirm that UiO-66 is thermally stable up to 500°C.
