Many metallic catalysts, especially precious metal catalysts are deposited as thin films on materials with a very high surface area. Why is this an effective way of utilizing the precious metal? (You can choose more than one)

a. If the catalyst is only present in a very thin layer, not very much is needed. This saves money.
b. Surface-deposited catalysts do not work; the whole catalyst material must be homogenous.
c. The material on which the catalyst is deposited causes alternative reactions to occur which would end up reducing percent yield.
d. Only the surface material reacts, so having the entire material be made of the catalyst is not necessary.

How does surface area affect reaction of a catalyst?

Increasing the surface area of a catalyst increases the frequency of collisions and increases the reaction rate.

Several smaller particles have more surface area than one large particle. The more surface area that is available for particles to collide, the faster the reaction will occur.

Thus, it is important way of utilizing the catalyst because only the surface material reacts, so having the entire material be made of the catalyst is not necessary.
