Water-in-oil microemulsions have been found to be good templates for synthesis of ZnO and ZnO@Ag nanoparticles and offered themselves as ideal ‘nanoreactors’ for uniform fabrication of core@shell nanoparticles.

Core Shell Nanoparticles

Silver nanoparticles (AgNPs) with mean diameter of 150 nm were synthesized by using an aqueous-basedreduction method. Ascorbic acid and sodium hydroxide (NaOH) were used as a reducing agent and as acatalyst, respectively. These AgNPs were subsequently coated with a layer of TiO2 to form Ag/TiO2 core-shellnanoparticles by using a sol-gel method. The particle sizes and morphology of Ag/TiO2 core-shellnanoparticles were characterized using scanning electron microscopy (SEM) and transition electronmicroscopy (TEM). The photocatalytic activity of the Ag/TiO2 core-shell nanoparticles were evaluated basedon the degradation of methylene blue (MB) as the model reaction. The TiO2 coating has resulted in theenhanced photocatalytic activity of Ag nanoparticles as compared to bare Ag nanoparticles.

New types of core–shell nanoparticles are reported: Pb@GaS fullerene-like and nanotubular structures, achieved via the continuously high reactor temperatures and ultra-hot strong-gradient annealing environments created by highly concentrated sunlight. Structural and chemical characterizations suggest a formation mechanism where vaporized Pb condenses into nanoparticles that are stabilized as they become covered by molten GaS, the ensuing crystallization of which creates the outer layers. Hollow-core GaS fullerene-like nanoparticles and nanotubes were also observed among the products, demonstrating that a single solar procedure can generate a variety of core–shell and hollow nanostructures. The proposed formation mechanisms can account for their relative abundance and the characterization data.
