“…It is used as a substrate for making nanocatalysts 19 . Given their large specific surface area, low density, and cheap cost, leached bimetallic nanostructures have recently attracted a lot of attention 20 – 23 . Palladium-based bimetallic catalysts exhibit better catalytic activity than palladium, according to research.…”

This paper introduces a unique and simple method for fabricating of inexpensive electrocatalysts for use in direct methanol fuel cells. The leached Fe1–Pd1 NFs/graphite (leached Fe1–Pd1/graphite) disk electrode was successfully obtained via uniform dispersion of Zn powder into the matrix of commercial graphite powder (98%), pressing under optimized pressure followed by the treatment in H2SO4 solution containing Fe+2 and Pd+2 cations, leading to the partial leaching out of Zn from graphite matrix, as well as partial electroless substitution of Fe–Pd nanoflakes with Zn metal. Based on the morphology studies, binary Fe–Pd nanoflakes with a large surface area uniformly dispersed on the leached graphite disk. The leached Fe–Pd/G disk showed the exceptional electrocatalytic activity toward methanol and formic acid oxidation without electrocatalyst poisoning being observed, in contrast to the leached Pd/graphite and leached Fe/graphite disks. This is due to the high surface area, and synergistic effect of Pd and Fe. The findings of this work may be used for the mass manufacture of graphite-based disks for commercial fuel cell applications using available graphite powders. The linear range of washed Fe1–Pd1/G electrocatalyst for measuring methanol was about 0.1–1.3 M, and its detection limit was calculated at about 0.03 M. Furthermore, the linear range of the nanocatalyst for measuring formic acid was about 0.02–0.1 M, and its detection limit was calculated at about 0.006 M.

This paper introduces a unique and simple method for making inexpensive electrocatalysts for use in direct methanol fuel cells. The leached Fe1-Pd1 NFs/graphite (leached Fe1-Pd1/G) disk electrode was successfully obtained via uniform dispersion of Zn powder into the matrix of commercial graphite powder (98%), pressing under optimized pressure followed by the treatment in H2SO4 solution containing Fe+2 and Pd+2 cations, leading to partial leaching out of Zn from graphite matrix as well as partial electroless substitution of Fe-Pd nanoflakes with Zn metal. According to morphology investigations, binary Fe-Pd nanoflakes with a large surface area developed evenly on the leached graphite disk. The leached Fe-Pd/G disk demonstrated exceptional electrocatalytic activity toward methanol and formic acid oxidation without electrocatalyst poisoning being observed, in contrast to the leached Pd /graphite and leached Fe /graphite disks. This is due to the high surface area and synergistic effect of Pd and Fe. The findings of this work may be used to the mass manufacture of graphite-based disks for commercial fuel cell applications using available graphite powders.
