title: Surface-metastable phase-initiated seeding and ostwald ripening: a facile fluorine-free process towards spherical fluffy core/shell, yolk/shell, and hollow anatase nanostructures.
abstract: Versatile synthetic method: Monodisperse anatase microspheres with various complex morphologies have been synthesized by using a versatile fluorine-free solvothermal process in the presence of ammonia. Unambiguous evidence related to surface seeding and a subsequent hollowing process revealed an Ostwald ripening evolution process.
