“…Other bimetallic clusters Pt–M (M = Ru, Ni, Co, Sn, and Au) were prepared by one-step gamma irradiation. Further, functional polymers (poly(vinylphenyl boronic acid) and poly(vinylpyrorridone)) were used to anchor these Pt–M nanoparticles on multiwalled carbon nanotubes using gamma irradiation in aqueous solution at room temperature . These materials were promising for direct methanol fuel cell electrode production.…”

This Review Article focuses on the highly versatile and effective method of radiolysis for the synthesis of nanoparticles (NPs). In particular, the formation of bimetallic and alloyed nanoparticles (or nanoalloys), including both known super alloys and novel alloy NP compositions, is described. This Review Article discloses the synthesis techniques that rely on ionizing radiation sources to create metallic NPs. Then, alloy NPs formed from combinations of transition metals and noble metals with varied structures are described. Some of the advantages of radiolysis including exquisite control over the size, monodispersity, and alloying structure of NPs are discussed. Additionally, methodologies that facilitate the synthesis or deposition of NPs onto a range of supports under inert environments are described. Finally, applications of metallic NPs formed by radiolysis are summarized.

“…[15,16] Yang et al synthesized a series of Pt-M NPs were deposited on the multi-walled carbon nanotube catalysts (M = Ru, Ni, Co, Sn, and Au) by a one-step radiation reaction, which shows a great commercial potential. [17] Moreover, ternary metallic nanocatalysts give more choices to synthesize efficient and multipurpose catalysts by enhanced the synergistic effects among them. However, controlled synthesis of these catalysts at large scale for enhanced efficiency and practical application is still in challenge.…”

The ternary FePtSn alloy nanoparticles (NPs) were synthesized via a simple programmed microfluidic process, showing a great electrochemical performance in methanol oxidation reaction (MOR). The synthesis process exhibited convenient and spatial-temporal kinetics control of the NPs formation for a narrow size distribution, ultra-small (~2nm) and good dispersion features. The morphology, crystal structure and composition of FePtSn NPs were characterized by transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDS), powder X-ray diffraction (XRD). FePtSn/C nanocatalyst ink could be further prepared by mixing the as-synthesized or annealed FePtSn NPs with carbon black powder and nafion. Their electrocatalytic performances were tested by the electrochemical work station. By contrast, the annealing treatment made more active sites exposed and facilitated the catalytic performance of FePtSn/C NPs. The electrochemical active surface areas (ECSAs, 42.8m2/g), catalytic activity (If: 588.1 mA/mg-Pt) and electrochemical durability of FePtSn/C nanocatalysts after annealing were greatly improved, comparing with as-synthesized samples and commercial Pt/C nanocatalysts for MOR. In addition, the onset potential of annealed FePtSn/C nanocatalysts was improved, much better than the commercial Pt/C nanocatalysts.
