Trimetallic Iron-Cobalt-Nickel (FeCoNi) Alloy as Electrocatalysts for Electrolyzer and Fuel Cell, 1 g/bottle, CEFCEFeCONi

Trimetallic FeCoNi alloys represent the pinnacle of non-precious transition metal electrocatalysts. By combining Nickel, Cobalt, and Iron, these alloys leverage a "triple synergy" that overcomes the limitations of bimetallic systems (like NiFe or NiCo), making them versatile for the three most critical reactions in renewable energy: OER, HER, and ORR.

FeCoNi alloys are the leading PGM-free candidates for industrial AEM water splitting. (1) Activity: Optimized alloys (e.g., Ni0.47Co0.35Fe0.18) can achieve overpotentials as low as 190–200 mV at 10 mA/cm2, which is superior to most commercial IrO2 benchmarks. (2) Stability: They exhibit exceptional corrosion resistance in concentrated KOH, maintaining stable performance for hundreds of hours even at high current densities (>200 mA/cm2).

FeCoNi is a highly efficient bifunctional catalyst for both the Oxygen Reduction Reaction (ORR) and the Oxygen Evolution Reaction (OER). FeCoNi-based air cathodes allow for efficient discharge (producing power) and recharge (regenerating the battery). They often reach power densities exceeding 130 mW/cm². Moreover, the presence of Co in FeCoNi significantly boosts the ORR kinetics, allowing for a smaller "voltage gap" between charging and discharging.

Notes: Please try to store the trimetallic FeCoNi powder in a dry place.
