Interaction of Chlorinated Ethylenes with Chromium Exchanged Zeolite Y: Anin SituFT-IR Study

Catalytic oxidation of 1,2-dichloroethane over three-dimensional ordered meso-macroporous Co3O4/La0.7Sr0.3Fe0.5Co0.5O3: Destruction route and mechanism

“…As shown in Fig. 12A, the surface species concentration over the 3DOM LSFCO is almost steady from 0 to 30 min and then gradually increases until to 90 min, indicating that 1,2-DCE is nearly adsorbed firstly and then began to band with the chemisorbed oxygen species on the surface of the sample [54]. Several bands at 3737, 3626, 3587 and 3566 cm −1 are assigned to the formation of H bonded hydroxyls [55], and the band at 1548 cm −1 is corresponded to ν(COO)ads of surface acetate species [56].…”

Nature of organic fluid–montmorillonite interactions: An FTIR spectroscopic study

“…10 shows the H-O-H bending region of the reflectance FTIR spectra of the MMT-TCE sample. Also seen are bands at 1590 and 1560 cm À1 that are the characteristic TCE IR bands from C@C vibrations [54,55]. It was observed that the H-O-H bending of MMT interlayer water shifts to higher energy by about 6 cm À1 immediately after mixing with TCE.…”

Catalytic combustion of chlorobenzene over VO /CeO2 catalysts

“…It can be expected that the formation of phenolate on CeO 2 is a nucleophilic substitution of basic surface lattice oxygen species for the chlorine atom. These bands become weak at 250°C, while new bands appear at 1367 and 1560 cm À1 (assigned to carbonate bidentate), and 1429 and 1541 cm À1 (asymmetric stretching vibration of carboxylates with the acetate type [21,[60][61][62]), indicating that phenolate is intermediate for CB oxidation over pure CeO 2 surface. Oxidation products were seen in the absence of gas-phase oxygen, indicating involvement of surface active oxygen in the oxidation process, as was reported earlier for other oxide catalysts [22,57].…”
