What is the role of a catalyst?
A substance that can change the rate of a chemical reaction (both increasing and decreasing) without altering the chemical equilibrium, and whose mass and chemical properties remain unchanged before and after the chemical reaction, is called a catalyst (solid catalysts are also known as promoters). According to statistics, catalysts are used in over 90% of industrial processes.

What is a catalyst? What are the basic properties of a catalyst?
The composition, chemical properties, and quality of the catalyst itself do not change before and after the reaction; its relationship with the reaction system is like that of a lock and key, exhibiting a high degree of selectivity (or specificity). A catalyst does not catalyze all chemical reactions; certain chemical reactions do not have only one unique catalyst.

Why do precious metal particle catalysts become deactivated?
Before regenerating deactivated precious metal particle catalysts, it is necessary to study and analyze the reasons for their deactivation. By testing various physicochemical properties of the deactivated catalyst samples (including component content, specific surface area, porosity, pore size distribution, crystal structure, strength, activity, etc.), the intrinsic reasons for the deactivation of the precious metal particle catalysts can be confirmed, providing a basis for catalyst regeneration.
