摘要
1D and 2D exchange C-13 NMR investigation of the states of methanol adsorbed on H-ZSM-5 at ambient temperature demonstrates the coexistence of methanol strongly interacting with Bronsted acid sites and methanol physisorbed or hydrogen-bonded, and provides the first spectroscopic evidence of a wide distribution in the strength of its interaction with Bronsted acid sites.
