Titania Derived from NH2-MIL-125(Ti) Metal–Organic Framework for Selective Photocatalytic Conversion of CO2 to Propylene Carbonate
ABSTRACT 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 °C, 500 °C, 550 °C, and 600 °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 °C, whereas the formation of TiO2 rutile phase at calcination temperature of 600 °C. The photocatalytic activities of produced TiO2 photocatalysts were investigated for the cycloaddition reaction of CO2 to propylene oxide.
期刊介绍：
Comments on Inorganic Chemistry is intended as a vehicle for authoritatively written critical discussions of inorganic chemistry research. We publish focused articles of any length that critique or comment upon new concepts, or which introduce new interpretations or developments of long-standing concepts. “Comments” may contain critical discussions of previously published work, or original research that critiques existing concepts or introduces novel concepts.
Through the medium of “comments,” the Editors encourage authors in any area of inorganic chemistry - synthesis, structure, spectroscopy, kinetics and mechanisms, theory - to write about their interests in a manner that is both personal and pedagogical. Comments is an excellent platform for younger inorganic chemists whose research is not yet widely known to describe their work, and add to the spectrum of Comments’ author profiles, which includes many well-established inorganic chemists.
