Can a noun be located in a prepositional phrase?
Yes, most of the time the object of a preposition is a noun. Sometimes it's a pronoun, but most of the time it's a noun.
Examples:
in the house
to the store
for my education
into Jane's house
because of my illness
In each of the above examples, the last word of each prepositional phrase is the object and each one is a noun.
