Titania Derived from NH2-MIL-125(Ti) Metal-Organic Framework for Selective Photocatalytic Conversion of CO2 to Propylene Carbonate

Titanium dioxide was prepared using titanium-based metal-organic framework (MOF) i.e., NH 2 -MIL-125(Ti) as a metal precursor. NH 2 -MIL-125(Ti) was synthesized then calcined at 400 °C, 500 °C, 550 °C, and 600 °C. The properties of NH 2 -MIL-125(Ti) and produced TiO 2 were investigated using various...

Description
Summary:Titanium dioxide was prepared using titanium-based metal-organic framework (MOF) i.e., NH 2 -MIL-125(Ti) as a metal precursor. NH 2 -MIL-125(Ti) was synthesized then calcined at 400 °C, 500 °C, 550 °C, and 600 °C. The properties of NH 2 -MIL-125(Ti) and produced TiO 2 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 TiO 2 anatase phase formation when Ti-MOF was calcined up to 500 °C, whereas the formation of TiO 2 rutile phase at calcination temperature of 600 °C. The photocatalytic activities of produced TiO 2 photocatalysts were investigated for the cycloaddition reaction of CO 2 to propylene oxide.
