Ethanol Electrooxidation Catalyzed by Tungsten Core@Palladium Shell Nanoparticles
Bimetallic nanostructures
represent effective electrocatalysts
toward a number of important reactions. In the present study, carbon-supported
palladium–tungsten alloy nanoparticles with a quasi-tungsten
core@palladium shell structure (W@Pd/C) were synthesized by a galvanic
replacement reaction of amorphous tungsten nanoparticles with Pd(II)
at different temperatures (0, 25, and 50 °C), and exhibited apparent
electrocatalytic activity toward ethanol oxidation reaction (EOR).
When the sample was prepared at 0 °C, large amorphous tungsten
nanoparticles were etched off and much smaller W@Pd nanoparticles
were formed and dispersed rather evenly on the carbon surface whereas
at higher reaction temperatures (25 and 50 °C), the W@Pd nanoparticles
became agglomerated. The structures of the obtained samples were characterized
by a range of experimental tools, including (scanning) transmission
electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy,
and electrochemical methods. Among the series, the W@Pd/C sample prepared
at 0 °C was observed to exhibit the best EOR performance, with
a mass activity (9535.5 mA mgPd–1) over three times better than that
of commercial Pd/C and markedly enhanced stability

Curved Porous PdCu Metallene as a High-Efficiency Bifunctional Electrocatalyst for Oxygen Reduction and Formic Acid Oxidation
Designing high-efficiency and newly developed Pd-based
bifunctional
catalytic materials still faces tremendous challenges for oxygen reduction
reaction (ORR) and formic acid oxidation reaction (FAO). Metallene
materials with unique structural features are considered strong candidates
for enhancing the catalytic performance. In this work, we synthesized
copper-doped two-dimensional curved porous Pd metallene nanomaterials via a simplistic one-pot solvothermal method. The updated
catalysts served as sturdy bifunctional electrocatalysts for cathodal
ORR and anodic FAO. In particular, the developed PdCu metallene exhibits
excellent half-wave potential (0.943 V vs RHE) and mass activity (MA)
(1.227 A mgPt–1) in alkaline solutions,
which are 1.09 and 6.26 times higher than those of commercial Pt/C,
respectively, indicating that the nanomaterials have abundant active
sites, displaying surpassing catalytic performance for oxygen reduction.
Furthermore, in an acidic formic acid electrolyte, PdCu metallene
exhibits prominent MA with a value of 0.905 A mgPd–1, which is 2.76 times that of commercial Pd/C. The
remarkable bifunctional catalytic performance of metallene materials
can be attributed to the special structure and electronic effects.
This work shows that metallene materials with curved and porous properties
provide a scientific idea for the development and design of efficient
and steady electrocatalysts
