A duplex receptacle is already two receptacles. The code section you are referring to restricts branch circuits serving a single receptacle only, in which case the receptacle rating has to be at least as large as the branch circuit rating. So a simplex receptacle on a 120V, 20A branch circuit would have to be a 5-20 or larger receptacle.
