A metal organic framework-supported Nickel nanoparticle (Ni-MOF-5) was successfully synthesized using a simple impregnation method. The obtained solid acid catalyst was characterized by Powder X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption-desorption and thermogravimetric analysis (TGA). The catalyst was highly crystalline with good thermodynamic stability (up to 400°C) and high surface area (699 m ). The catalyst was studied for the oxidation of ethyl benzene, and the results were monitored via gas chromatography (GC) and found that the Ni-MOF-5 catalyst was highly effective for ethyl benzene oxidation. The conversion of ethyl benzene and the selectivity for acetophenone were 55.3% and 90.2%, respectively.

Abstract. In this work, Cu 3 (BTC) 2 (Cu-BTC) metal organic framework (MOF), also known as HKUST-1, was prepared by 3 different synthetic route. The synthesized Cu-BTC materials were characterized by powder X-ray diffraction (XRD) for phase structure, scanning electron microscopy (SEM) for crystal structure, thermogravimetric analysis (TGA) for thermal stability, and nitrogen adsorption-desorption for pore textural structure. The results showed that the sample synthesized by microwave method has the high surface area and pore volume of 1721 m 2 g -1 and 0.7424 cm 3 g -1 , respectively. Among the three synthetic methods, the sample synthesized by microwave method exhibited a CO 2 uptake of 23.3% at 25 °C and ambient pressure.

Abstract

Novel amine loaded poly (vinyl benzyl chloride-co divinyl benzene) polymer was synthesized successfully and studied for its CO 2 adsorption and moisture adsorbing efficiency. The poly Vbcl DVB co polymer was loaded with tris (2-aminoethyl) amine in different wt %. Then they were characterized with various physiochemical techniques such as thermo gravimetric analysis (TGA), FT-IR, diffuse reflectance UV spectroscopy (DRS-UV), differeential scanning calorimetric (DSC). Results shown that the polymer synthesized was stable up to 400 °C and can adsorb 4.5 and 6 wt % CO 2 and water at room temperature.
