The Adsorption of Formic Acid on Y Zeolites: An Infrared Absorbance Study.

Abstract

The adsorption of formic acid on an ammonium-Y (NH4-Y) zeolite and an ultrastable hydrogen-Y (H-Y) zeolite has been studied with transmission infrared spectroscopy. The formic acid is determined to be chemically adsorbed on both zeolites as bidentate formate ions and as covalently bonded unidentate formate species. Assuming uniform infrared extinction coefficients for the two adsorbed formates, the NH4-Y zeolite has comparable amounts of each surface species. (Author)
