Abstract:

The catalytic performance of zeolite is mainly dependent on its acidic properties. The accurately and quantitatively distinguishing acid type, density, strength and site distribution of acid is significant to clarify the catalytic performance of zeolites. Here, we summarize the recent advances in the qualitative and quantitative analytic methods for acid site distribution, acid type and acid strengths.

Key words: zeolite, acid properties, characterization method, Brønsted acid
