Interactions between chemisorbed carbon monoxide molecules and surface hydroxyl groups of the support in Pt/ Al2O3 and Pt/SiO2 catalysts were studied by using FTIR spectroscopy. Infrared spectra of the catalysts were measured both before and after the adsorption of CO. Due to the adsorption of CO. the intense 3700-3000 cm-1 band. https://www.diegojavierfares.com/mega-save-8-tall-Faux-Crystal-Beaded-Candle-Holder-Centerpiece-great-buy/
