Classification: CPC C  B | IPC B  C

Claim 13:
14. A method of synthesizing metallic nanoparticles, the method comprising
dispersing, in a reactor, a branched polymeric template mixed with mesoporous silica that provides a surface-area substrate to support growth of metallic nanoparticles of a transition metal in the branched polymeric template, wherein the branched polymeric template is not a dendrimer;
providing to the reactor a first flow stream comprising an aqueous metal salt solution comprising ions of the transition metal;
admitting ultraviolet (UV) light through an optical port of the reactor to cause photoreduction of the transition metal ions in the metal salt solution;
reducing in the reactor the ions of the transition metal ions in the metal salt solution using the UV light; and
separating the metallic nanoparticles from the branched polymeric template using a purification method comprising a ligand exchange reaction.
