Pt‐Pd Nanoalloys Functionalized Mesoporous SnO2 Spheres: Tailored Synthesis, Sensing Mechanism, and Device Integration

“…[ 37,38 ] The high‐angle annular dark field scanning transmission electron microscopy (HAADF‐STEM) shows the homogeneous distribution of ultra‐small Pt‐Pd NPs (Figure 1e), and the line‐scanning Pt and Pd concentration profiles across a single Pt‐Pd NPs indicate that the noble metal NPs are comprised of both Pt and Pd atoms, which provides additional evidence for the existence of Pt‐Pd nanoalloys (Figure 1f). [ 39 ] In addition, the corresponding energy‐dispersive spectrometric (EDS) elemental mapping further confirms the homogeneously distributed Sn, O, Pt, and Pd (Figure 1g).…”

Synergistic effect of bimetallic Pd–Pt nanocrystals for highly efficient methanol oxidation electrocatalysts

“…[31][32][33] Among various metals for the formation of Pt-based bimetallic NCs, Pd is recognized for its capability to augment the MOR activity and durability of Ptbased catalysts. [34][35][36][37] Given this background, Pd-Pt bimetallic NCs are widely regarded as highly promising candidates for efficient electrocatalysis in the MOR. However, the preparation of Pd-Pt bimetallic NCs with precisely controlled compositional structures and the in-depth investigation of their MOR properties have been rarely explored to date.…”

Phosphorus‐doped Pt nanowires as efficient catalysts for electrochemical hydrogen evolution and methanol oxidation reaction

“…Pt is an effective electrocatalyst for the hydrogen evolution reaction (HER) and fuel oxidation reactions in polymer electrolyte membrane fuel cells (PEMFCs) 1–6 . However, Pt‐based catalysts possess limitations as electrocatalysts for practical HER and PEMFC applications due to their high cost, scarcity, and deficient electrochemical durability 7–9 . Furthermore, Pt surfaces are severely susceptible to surface poisoning effect by intermediates 10–12 .…”

“…[1][2][3][4][5][6] However, Pt-based catalysts possess limitations as electrocatalysts for practical HER and PEMFC applications due to their high cost, scarcity, and deficient electrochemical durability. [7][8][9] Furthermore, Pt surfaces are severely susceptible to surface poisoning effect by intermediates. [10][11][12] Thus, reducing the cost and enhancing the activity and stability of the catalysts are crucial.…”
