You activate it by either clicking the Zhonya's item in your inventory in the bottom left corner of the UI, or by pressing the number that correspond with the slot. 1-6 are designated tp Active Ability Items by default.

Also, using zhonya's activate ability will not cause morgana's ultimate to cancel. So yes, you can use it with morg.
