What is the difference between a catalyst and a promoter?

Asked by mkp400 21st October 2017, 8:23 PM
Answered by Expert
A catalyst is a substance which decreases the activation energy of a chemical reaction without itself being changed at the end of the chemical reaction.
A promoter is an accelerator of catalysis, but not a catalyst by itself.
Promoter is a material that enhances the action of a catalyst without actually having any catalytic value itself.
