Abstract

The need to reduce global reliance on fossil fuels by the use of alternative technologies has pushed hydrogen to the forefront of gas storage applications. This research is focused on a metal organic framework material, MOF-5, which has appealed to a number of scientists for application in hydrogen storage. However, MOF synthesis often requires expensive starting materials. Cheaper sources of starting materials need to be identified if economical large-scale use of MOFs is to become practically feasible. In this research, MOF-5 was prepared by solvothermal method and using spent terephthalic acid (TPA) waste from PetroVietnam Petrochemical and Textile Fiber Joint Stock Company (PVTex) as a starting material. Products in this research were then characterized by X-Ray diffraction (XRD), Infrared Spectroscopy (IR), Thermogravimetric analysis (TGA), Scanning electron microscopy (SEM) and Brunauer–Emmett–Teller (BET) surface area analysis. The results showed typical cubic crystals from SEM analysis, and XRD analysis of the synthesized sample showed peaks consistent with the published structure of MOF-5. In addition, with the high porosity and high thermal stability, this material will have prospective application in hydrogen storage, demonstrating that waste TPA has potential for use as a sustainable starting material for synthesis of MOFs for gas storage.
