A catalyst promoter_________________?
Correct answer: A. Improves the activity of a catalyst
- A. Improves the activity of a catalyst
- B. Acts as a catalyst support
- C. Itself has very high activity
- D. All A., B. and C.
Explanation
A promoter is an additive that improves a catalyst's activity, selectivity, or stability, although it may have little catalytic activity by itself. It is therefore not the same as a catalyst support.
