DRIFTS investigation of methanol oxidation on CeO2 nanoparticles

Effect of the Zr/Al Molar Ratio on the Performance of Cu/ZrO2–Al2O3 Catalysts for Methanol Steam Reforming

“…The IR bands at 3663 and 1461 cm –1 are, respectively, assigned to the stretching vibrations and symmetric bending of O–H in the absorbed methanol . Another IR bands at 3735 cm –1 is ascribed to the surface −OH group . The IR bands at 2300–2400 cm –1 correspond to the asymmetric stretching of CO 2 . − As the reaction time lengthened, the IR bands of CO 2 became stronger.…”

“…62 Another IR bands at 3735 cm −1 is ascribed to the surface −OH group. 63 The IR bands at 2300−2400 cm −1 correspond to the asymmetric stretching of CO 2 . 64−66 As the reaction time lengthened, the IR bands of CO 2 became stronger.…”

“…49 The inverted peak at 3734 cm À1 can be ascribed to the consumption of the surface -OH group. 50 Relevant information is summarized in Table S2. †…”

In Situ DRIFTS-MS Methanol Adsorption Study onto Supported NiSn Nanoparticles: Mechanistic Implications in Methanol Steam Reforming

“…In order to identify the active species and relate their formation with the surface catalyst properties as well as to obtain useful information for the preparation of more effective catalysts, we have performed an in situ diffuse reflectance infrared Fourier transform spectroscopy coupled to mass spectrometry (DRIFTS-MS) study of methanol adsorption under reaction conditions. Previous studies have demonstrated that DRIFTS is a powerful tool for monitoring catalytic surface chemistry before, during, and after adsorbate introduction [20]. This work provides information insights into the interaction of methanol with the surface of the catalyst and allows the elucidation of the reaction mechanism following the involved species during the reaction.…”
