Near infrared study on the adsorption states of NH 3 and NH 4 + on hydrated ZSM-5 zeolites

In order to understand the acidity properties of hydrated ZSM-5 zeolites having different SiO 2 /Al 2 O 3 ratios, the adsorption states of the NH 3 and NH 4 + species on hydrated ZSM-5 zeolites were concurrently investigated by near infrared spectroscopy. In the case of hydrated H + -type ZSM-5, abs...
