Claim 0:
1. 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 within 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 a transition metal;
providing to the reactor a second flow stream comprising a chemical reducing agent to reduce the ions of the transition metal to form metallic nanoparticles within the branched polymeric template;
reducing in the reactor the ions of the transition metal ions in the metal salt solution; and
separating the metallic nanoparticles from the branched polymeric template using a purification method selected from the group consisting of a ligand exchange reaction, diafiltration, or oxygen plasma.
