摘要：

Titanium dioxide was prepared using titanium-based metal-organic framework (MOF) i.e., NH2-MIL-125(Ti) as a metal precursor. NH2-MIL-125(Ti) was synthesized then calcined at 400 degrees C, 500 degrees C, 550 degrees C, and 600 degrees C. The properties of NH2-MIL-125(Ti) and produced TiO2 were investigated using various techniques, including powder X-ray diffraction (PXRD), Brunauer-Emmett-Teller (BET), and UV-visible diffuse reflectance spectroscopy (UV-Vis DRS). A scanning electron microscopy (SEM) was used to observe surface morphology and energy-dispersive X-ray spectroscopy (EDX) to analyze elemental composition of prepared samples. PXRD pattern confirms TiO2 anatase phase formation when Ti-MOF was calcined up to 500 degrees C, whereas the formation of TiO2 rutile phase at calcination temperature of 600 degrees C. The photocatalytic activities of produced TiO2 photocatalysts were investigated for the cycloaddition reaction of CO2 to propylene oxide.
