Fabrication of NiCu interconnected porous nanostructures for highly selective methanol oxidation coupled with hydrogen evolution reaction

Electrocatalytic water electrolysis is the most promising clean and efficient process for pure generation of hydrogen. However, oxidation reaction requires a large overpotential owing to its slow kinetics, causing lower efficiency hydrogen production high energy consumption. Herein, we report bimetallic NiCu interconnected porous nanostructures on copper foil ([email protected]) prepared by bubbles templating electrodeposition technique methanol (MOR), which replaces kinetically sluggish enhances with input. With their macroporosity, growth excellent conductivity easy flow electrolyte electrode interface, stabilization active sites due synergistic effects, [email protected] electrocatalysts exhibit outstanding activities HER MOR. The requiring just 1.32 V anodic potential vs RHE at 10 mA cm?2 MOR significantly than that reaction. Moreover, electrolyzer using protected]/[email cathodic H2 only needs low input voltage 1.45 deliver current density impressive durability.
