Yes he can and it acts like a black hole, however how it works varies between the anime and manga. In the anime, The Angel Arm cannot destroy organic beings, however it will completly erase all inorganic material away, so basically all of Cad Bane's weapon and armory are gone from existence. In the manga, it acts like an actual black hole and erases everything from existence on the premisies.
