Abstract |
Microwave (MW) heating has received a considerable attention as a new promising method for the synthesis of metallic nanostructures in solutions. In this review, advantageous application of this metho...d has been demonstrated by using typical examples for the preparation of Au, Ag, Au@Ag, and Pt/C nanostructures. No only spherical nanoparticles, but also single crystalline polygonal sheets, plates, rods, wires, and core-shell structures were prepared within a few minutes under MW heating. Morphologies and sizes of nanostructures could be controlled by changing various experimental parameters, such as concentrations of metallic salt and surfactant polymer, chain length of the surfactant polymer, and solvent. In general, nanostructures with smaller sizes, narrower size distributions, and higher degree of crystallization were obtained under MW heating than those in conventional oil-bath heating.show more
