ZnS nanotubes and tubular ZnO/ZnS core/shell nanocomposites can be successfully synthesized via a facile conversion process from ZnO nanorods precursors. The photoluminescence (PL) characterization of the as-prepared products shows much enhanced PL emission of tubular ZnO/ZnS core/shell nanocomposites compared with their component counterparts.

The electromagnetic parameters (ε′, ε″, μ′, and μ″) of /PPy core-shell nanoparticles exhibit much difference from those of ZnFe2O4 and correspondingly the minimum reflection loss increases from −10.7 of ZnFe2O4 nanoparticles to −28.9 dB of ZnFe2O4/PPy core-shell nanoparticles.

The influences of different kinds of inorganic and organic salts on the morphologies of ZnO microstructures prepared via a facile hydrothermal route have been investigated. It is found that sulfates exhibit most distinct effect on the morphologies of final products. The possible mechanism for the phenomenon has been proposed. The dependence of photoluminescence (PL) properties on morphologies and sizes of final products has been clearly observed. This work may provide a new and effective means to tune the morphologies of products by introducing specific ions into the synthetic process.

Hollow bimetallic (Ni/Au, Ni/Ag, Ni/Pt and Ni/Pd) and noble metal (Pt and Pd) spheres can be selectively prepared by adjusting the amount of noble metal compound and hollow metallic nickel spheres based on a replacement reaction route. The study on catalytic activities of the as-prepared hollow noble metal spheres for hydrogen generation reveals that Ni/Pt hollow bimetallic spheres exhibit favorable catalytic activities.
