Abstract
Porous Ni–Pt and Ni–Pt–Ni electrocatalysts were produced by molten-salt aluminium deposition and dissolution, which created continuous porous foams with high internal surface area. Structural analysis confirmed that the simple Ni–Pt bilayer evolves into a Pt-rich surface, and the sandwich Ni–Pt–Ni architecture retains most of the Pt within the porous structure. Catalytic tests reveals differences in HER (Hydrogen Evolution Reaction) and OER (Oxygen Evolution Reaction) kinetics: the Ni–Pt foam reaches −100 mA cm−2 for HER at −102 mV and displays a low Tafel slope of 32.2 mV dec−1, while the Ni–Pt–Ni foam requires −179 mV and shows 42.6 mV dec−1. Both Pt-containing foams also reduce the OER overpotential to ≈+1.69 V at +100 mA cm−2. The results demonstrate that maximising Pt exposure in the interface area is key to tailoring noble-metal performance materials for water splitting applications.
