Implication

Research investigates the effectiveness of zirconia-carbon electrocatalysts in enhancing oxygen reduction reactions, suggesting a viable alternative to high-platinum catalysts.

Key Points

The aim is to develop low-platinum electrocatalysts for improved efficiency in oxygen reduction reactions in fuel cells.
Prepared zirconium dioxide-carbon composite from UiO‐66 via pyrolysis at varying temperatures.
Deposited platinum nanoparticles onto the composite framework using ethylene glycol as a reducing agent.
Evaluated electrocatalytic activity through mass activity comparisons with commercial Pt/C catalysts.
Pt/U‐800 catalyst exhibited the highest mass activity at 796.9 mA mg Pt −1, exceeding commercial Pt/C by 3.64 times.
Achieved a peak power density of 1820 mW cm −2 in fuel cell tests.
The interfacial structure between ZrO 2 and Pt enhanced the electrocatalytic performance.
