We proposed a facile method to prepare ZnO@g-C3N4 core/shell type photocatalyst via a two-step calcination. Thin layer of g-C3N4 was homogeneously coated on ZnO nanoparticles with well-defined interface, which reduces the charge transfer resistance and results in distinct PL quenching. Therefore, the as-prepared ZnO@g-C3N4 demonstrates significant photocatalytic improvement under visible-light irradiation...
One-dimensional (1D) CdS@ZnS core-shell nanocomposites were successfully synthesized via a two-step solvothermal method. Preformed CdS nanowires with a diameter of ca. 45 nm and a length up to several tens of micrometers were coated with a layer of ZnS shell by the reaction of zinc acetate and thiourea at 180 °C for 10 h. It was found that uniform ZnS shell was composed of ZnS nanoparticles with a...
In this paper, AC breakdown (ACBD) properties of nano-Ag/epoxy resin composites were studied. The result shows that the ACBD strength value has a peak with the increase of Ag particles. This phenomenon can be explained by basic dielectric theories and Coulomb blockade mechanism. The ACBD strength values of the composites can be described by a Weibull distribution, and the Weibull parameters have a...
