Hollow and filled Ni microspheres are fabricated by a photocatalytic approach using polyelectrolyte capsules as templates. Because of the different crystallization conditions existing in the capsule shell and the interior volume, Ni nanorods are formed inside the capsule, whereas only small, spherical Ni nanoparticles are obtained in the capsule shell (see Figure). The metallized polyelectrolyte shell is sensitive to the pH and possesses pH‐controlled permeability.
