What do you mean by this? If you mean "How to create a clone of a database from standby database", see bellow.
Again same question from my side, what do you mean by "cloning from recovery catalog"? If you are connected to recovery catalog, it will be used during clone operation. By the way, why this question is bothering you and how will it make any difference?
You can use a recovery catalog when doing a cloning / DUPLICATE.
Note, however, the 10.2 restrictions on the DUPLICATE Command : http://docs.oracle.com/cd/B19306_01/backup.102/b14194/rcmsynta028.htm#RCMRF126
You must be connected to both the target database and auxiliary instance. The auxiliary instance must be started with the NOMOUNT option, and the target database must be mounted or open. The target database cannot be a standby database.
