ZnO/Ag composite nanospheres with an average diameter of about 440nm,
were synthesized through a facile one-pot solvothermal reaction, using a
kind of biomolecular sodium alginate as template, H"2O and diethanolamine
as solvents, followed by the assembly of ZnO and Ag nanoparticles in-situly
produced. The composite spheres were characterized by X-ray diffraction,
scanning electron microscopy, transmission electron microscopy, and energy
disperse X-ray spectrum. Moreover, the results showed that the as-made
ZnO/Ag assembled nanospheres exhibited better photocatalytic performance
than the pure ZnO nanoparticles and this one-pot synthesis method has great
potential to be extended for the synthesis of other metallic oxide/metal
spheres.
