Multicomponent Pt-based nanowires (NWs) have attracted widespread attentiona se letrocatalysts toward direct alcohol fuel cells because of their unique one-dimensional structure and high reactiond ynamics. Quaternary PtPdAuTeN Ws are designedv ia af acile template method, and NWs with ad ifferent composition are obtained by adjusting the feed ratio of metal precursors. The direct displacement reactiono fm etal precursors with Te NWsa nd the partial oxidation of Te lead to the formation of quaternary NWs. The rough surfacea nd abundant reactive sites deriving from the rearrangement of metal atoms on the Te NWs surface endow the PtPdAuTeN Ws with as uperior electrocatalytic propertya nd durability for methanol oxidation. The Pt 20 Pd 20 Au 10 Te 50 NWs display the largestm ass activity and best stabilitya mong all catalysts. The preparation of PtPdAuTeNWs could provideaviable strategy for the preparation of other multicomponent NWs.Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.

“…Therefore, the nal morphology of these PdPt bimetallic alloy nanowires are able to be inuenced by either Te nanowires template or the Pd element in the alloy nanostructure in a certain extent. 38 The high Pt 0 /Pt 2+ and Pd 0 /Pd 2+ intensity ratio indicate that the Pt 0 and Pd 0 species are the dominant in the PdPt-1:1 BANWs. 31 To further investigate the PdPt-1:1 BANWs composition and valence state of materials, the wide scan survey X-ray photoelectron spectrum (XPS) of PdPt-1:1 BANWs and high resolution spectra of the Pd and Pt elements were recorded.…”

One-dimensional (1D) bimetallic nanowire materials have attracted much more attention in electroanalysis because of their unique physical and chemical properties. In this work, we further extended the application field of the PdPt bimetallic alloy nanowires (PdPt BANWs) structure and successfully fabricated a novel PdPt BANWs-based electrochemical sensor for sensitive detection of ascorbic acid (AA). It was found that the PdPt BANWs on the electrode exhibited remarkable electrocatalytic activity toward AA oxidation and could be used for sensitive detection of AA in a wide linear range (0.01-0.97 mM) with a high sensitivity of 467.9 mA mM À1 cm À2 . The detection limit is as lower as 0.2 mM (S/N ¼ 3). Moreover, the electrochemical sensor also exhibited good selectivity, reproducibility and stability, and had been successfully applied to detection of AA in serum samples and commercial vitamin C tablets with satisfactory results.

“…The dispersed metal nanotubes used for the network buildup can be obtained by various methods. Galvanic replacement of colloidal silver, copper, or tellurium nanowires with a more noble metal (e.g., Pt [11,[55][56][57], Pd [56,58], Au [58]) or metal combinations (e.g., Au-Pt [59], Pd-Pt [11,56], Pt-Ru [60]) is a common approach. It should be considered that even in the case of replacement with a single metal, the commonly occurring incompleteness of the exchange reaction-and/or accompanying purification steps intended to remove the residual educt metal-will result in bimetallic systems, in which a considerable impact of the composition on the catalytic performance is to be expected [61].…”

Combining 1D metal nanotubes and nanowires into cross-linked 2D and 3D architectures represents an attractive design strategy for creating tailored unsupported catalysts. Such materials complement the functionality and high surface area of the nanoscale building blocks with the stability, continuous conduction pathways, efficient mass transfer, and convenient handling of a free-standing, interconnected, open-porous superstructure. This review summarizes synthetic approaches toward metal nano-networks of varying dimensionality, including the assembly of colloidal 1D nanostructures, the buildup of nanofibrous networks by electrospinning, and direct, template-assisted deposition methods. It is outlined how the nanostructure, porosity, network architecture, and composition of such materials can be tuned by the fabrication conditions and additional processing steps. Finally, it is shown how these synthetic tools can be employed for designing and optimizing self-supported metal nano-networks for application in electrocatalysis and related fields.
