The Adsorption of Formic Acid on Y Zeolites: A Nuclear Magnetic Resonance Study.

Abstract

A solid state nuclear magnetic resonance (NMR) study of the adsorption of formic acid on ammonium-Y (NH4-Y) and ultrastable hydrogen-Y (H-Y) zeolites confirms the results of a previously reported infrared study and provides a further description of the adsorbed states. The formic acid is adsorbed on the NH4-Y and ultrastable H-Y zeolites in two different forms; as a unidentate formate ligand and as a bidentate formate species, as determined by the sy-metry of the chemical shift powder patterns.
