Core/shell sub-ten-nanometer metal nanoparticles with controllable thin Pt shell have been synthesized through an interface-mediated galvanic displacement reaction between monodisperse hydrophobic Au@Ag or Ag nanoparticles and a platinum salt in aqueous solution. Through oil-ethanol-H2O interface mediation, the galvanic displacement of Ag atoms with Pt can be achieved by facile control of the reaction kinetics. The Pt atoms have a high exposure ratio which leads to potential catalytic applications, such as oxygen reduction.

Silicon (Si) NW arrays have been employed as a model photocathode system for MoS2 wrapping, and their solar-driven hydrogen evolution reaction (HER) activity was evaluated. The photocathode comprises a well-defined MoS2/TiO2/Si coaxial NW heterostructure, which yielded photocurrent density up to 15 mA/cm2 at 0 V (vs. the reversible hydrogen electrode (RHE)) with good stability under the operating conditions employed.

The low yield of high-quality carbon nanotubes is caused by the rapid deactivation of the catalyst at high temperature. Modification of catalyst composition can significantly elongate the catalyst lifetime and improve the yield of high-quality carbon nanotubes.

When illuminated by light, the nanometer or sub-nanometer interfacial layer of condensed molecules surrounding individual nanomaterials will behave as an optical dipole lattice and contribute an instantaneous near field to enhance the local field acting on nanomaterials. This interface dipole enhancement effect leads to enhanced Rayleigh scattering which not only enables true-color real-time imaging of nanomaterials, but also provides an effective means to peer into the subtle interfacial phenomena.
