催化反应中催化剂的用量对催化效率的影响有多大？

generally will result in higher reactivity, but may not be in linear

higher surface area and then the higher efficiencies.

the reaction rate by the weight of catalyst. Ideally you need to normalize
by # of surface atoms.

Higher specific surface area generally will result in higher reactivity, but
may not be in linear relationship.
