Synthesis and Characterization of Iron, Titanium and their Mixture with Benzene-1,3,5-Tricarboxylic Acid Framework

Metal-organic frameworks (MOFs, also known as coordination polymers), are a new class of crystalline porous materials that consist of metal centers and/or metal clusters connected by organic linkers. This project is concerned with the synthesizing and characterization of mixed-metal metal-organic frameworks (MM-MOFs) of 1,3,5-Tri-Carboxylic Acid Benzene (BTC), M-Fe-BTC, where M = Ti+3, by using the Solvothermal method. The MM-MOFs' powder X-ray diffraction patterns were similar to those of MIL (100). The results of scanning electron microscopy show that most of them are nanomaterials. The six samples had varying amounts of iron and titanium, according to the EDX results. The FT-IR results support the XRD outcomes. Thermal analysis demonstrates multiple stages of decomposition, and the materials show thermal stability up to 450 °C. UV-Vis Diffuse Reflectance confirmed that all samples, with the exception of sample No. 1 (insulator), are semiconductors.
