Abstract

The present work is a novel technique of synthesis and characterization of MOF based photocatalyst for carbon dioxide conversion. Visible light was used for irradiation. Cu3BTC2 MOF with large specific surface area (BTC = benzene-1,3,5-tricarboxylate) was synthesized by hydrothermal method and co-ordination modulation method. It was then used as a starting material for the preparation of a MOF based photo catalyst containing titanium dioxide. This photo catalyst, TiO2@Cu3BTC2, was prepared by hydrolysis of Titanium (IV) iso-propoxide under hydrothermal conditions. The synthesized MOF was then characterized by X-ray diffraction (XRD), Thermogravimetric analysis (TGA) and Brunauer–Emmett–Teller (BET) techniques. It was noted that TiO2@Cu3BTC2 exhibits very strong photo catalytic activity in comparison with TiO2 nanoparticles and this modified form of the photo catalyst could be used in the conversion of carbon dioxide to methanol. Additionally, a MOF based membrane was synthesized using soil and first dip coating procedure. After characterization of membrane, it was observed that the nucleation density of MOF directly on clay based support is very low. Treatment of membrane with alumina could increase the coverage of MOF particles as it provides a better activated surface.
