Abstract

Acid catalyst has been widely used and well-studied in chemical process and their catalytic activities are normally dictated by their acidities. Determination of acidity of acid catalyst, such as type, amount (concentration), and strength, are the great significance for achieving desired results of catalytic reactions. In this mini review, the characterization methods for acid type, acid amount, acid strength and their recent progresses were summarized, and the merits and disadvantages of each method were also reviewed with specific focus on the progress of the three characterization methods in acid type, structure and application of the catalysts. It is of great significance to help readers fully understand the mechanism of acid catalysis and select suitable catalysts.
