In the present study, for the first time Cu-core/CuSO4-shell nanoparticles were prepared through a microwave-assisted route. Sodium dodecyl sulfate (SDS) played role as a surfactant and sulfur precursor to produce Cu@CuSO4 nanoparticles. CuSO4 shell is uniformly coated on the whole surface of Cu nanoparticles. The obtained Cu@CuSO4 nanoparticles exhibited higher photocatalytic efficiency than Cu nanoparticles...
Hollow structures are attracting increasing attention due to their unique properties and potential applications in many fields. Despite the great successes achieved in the synthesis of hollow spheres, the preparation of nonspherical hollow structures still remains a great challenge. In this paper, we developed a facile method to prepare hematite hollow structures with cocoon-like shape. The as-prepared...
