Fourier transform infrared-temperature programmed structure

Characterization of the catalysts was made using high-resolution transmission electron microscopy (TEM) (Hitachi H-9000), X-ray diffraction (XRD), extended X-ray absorption fine structure (EXAFS), X-ray photoelectron spectroscopy (XPS), temperature programmed desorption (TPD), and Fourier transform-infrared spectroscopy (FT-IR).

Temperature-programmed desorption (TPD) and Fourier transform infrared spectroscopy (FTIR) have been used to investigate the structure and environment... [Pg.882]

Further on, different ILs with various structures were confined into the supercage of silica gel and extensively characterized by Brunauer-Emmett-Teller (BET), Fourier transform infrared spectroscopy (FT-IR), temperature-programmed desorption (TPD), differential scanning calorimetry (DSC), and inverse gas chromatography (ICC) [67]. Compared to the bulk IL and silica gel-supported IL film, the silica gel-confined IL displayed remarkably low specific heat capacities, disordered vibrational conformations, stronger interactions with hydrocarbon solutes, and greatly enhanced fluorescence emission. Furthermore, it could be applied in the separation of CO2 from CO2/N2 mixtures and thiophene from thiophene/octane mixtures. [Pg.56]
