Nitrogen physisorption measurements

Coordination-driven self-assembly of nickel (II) ions with equimolar amounts of 1, 10 phenanthroline, and benzoic acid was used to create homonuclear nickel (II) MOF-type supramolecule. Single crystal X-ray diffraction, scanning electron microscopy, differential scanning calorimetry, photoluminescence measurement, FT-IR, UV-visible spectroscopy, and nitrogen physisorption measurement were used to characterize the compound. The single crystal X-ray diffraction study reveals that the synthesized compound is twodimensional with pores in the structure.

CeO2–ZrO2-composed NiO and Co3O4 catalysts were prepared by 3 different methods. Both CO methanation and selective CO methanation were carried out. All catalysts were prepared by (1) co-precipitation, (2) surfactantassisted co-precipitation, and (3) surfactant-assisted co-precipitation with ultrasound mixing methods. Catalysts were characterized by using N2 physisorption, XRD, SEM, TEM, and TPR-H2 techniques. The highest surface area value, uniform pore size distribution, and pores having small diameters were observed for the catalysts prepared by using the surfactant and ultrasound.

The amino-functionalized SBA-15 was allowed to react with 2-acetyl pyridine to form an immobilized bidentate iminopyridine ligand, which was complexed with palladium acetate, affording the immobilized palladium complex catalyst with a palladium loading of 0.4 mmol/g (AAS). The catalyst was characterized by X-ray powder diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR), nitrogen physisorption measurements, and elemental analysis (EA).

Ammonia functionalized UiO66 (UiO66–NH2) in the form of thin film was synthesized by a solvothermal method combined with a dip–coating technique and determined with physicochemical characteristics by X–ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen physisorption measurements (BET), infrared spectroscopy (IR), thermogravimetric analysis (TGA), and ultraviolet–visible diffuse reflectance spectroscopy (UV–Vis DRS).
