Special Issue Information

Dear Colleagues,

In recent decades, metal nanomaterials have been extensively studied and validated, with many promising applications in the fields of catalysis, optics, plasmonics, sensing, and biomedical applications, among others. In this Special Issue, we focus on the discussion of the synthesis and application of metal nanomaterials. Contributions could include, but are not limited to, the following topics:

  • Advanced synthethic strategies to create metal nanocrystals with niche shapes that are rare among previous reports, and the investigation of the mechanism of formation.
  • Applications of multimetallic nanomaterials with tailored sizes/shapes in electrocatalytic and photocatalytic reactions.
  • Development of functional plasmonic metal nanomaterials with multimode optical absorptions for efficient photothermal conversion.
  • Self-standing 3D architectures (e.g., membranes, coatings, films, and aerogels) fabricated using metal nanomaterials as the building blocks.
  • Rational design of hybrid metal nanostructures (e.g., core–shell and Janus) and analyses of their structural advantages in electrocatalytic and photocatalytic applications.
  • Investigation of the metal nanoparticle stability in terms of shape and structure, as well as the atomic diffusion pattern under controlled conditions.
  • Construction and applications of biosurfaces (e.g., interfaces, films, and membranes) containing metal nanomaterials.

The formic acid oxidation reaction (FAOR) represents an important class of small organic molecule oxidation and is central to the practical application of fuel cells. In this study, we report the fabrication of Ir(IV)-doped PdAg alloy nanodendrites with sub-5 nm branches via stepwise synthesis in which the precursors of Pd and Ag were co-reduced, followed by the addition of IrCl3 to conduct an in situ galvanic replacement reaction. When serving as the electrocatalyst for the FAOR in an acidic medium, Ir(IV) doping unambiguously enhanced the activity of PdAg alloy nanodendrites and improved the reaction kinetics and long-term stability. In particular, the carbon-supported PdAgIr nanodendrites exhibited a prominent mass activity with a value of 1.09 A mgPd−1, which is almost 2.0 times and 2.7 times that of their PdAg and Pd counterparts, and far superior to that of commercial Pt/C. As confirmed by the means of the DFT simulations, this improved electrocatalytic performance stems from the reduced overall barrier in the oxidation of formic acid into CO2 during the FAOR and successful d-band tuning, together with the stabilization of Pd atoms. The current study opens a new avenue for engineering Pd-based trimetallic nanocrystals with versatile control over the morphology and composition, shedding light on the design of advanced fuel cell electrocatalysts.
