⚙️ Youveim® E150 NiFe-LDH@Nickel Fiber Paper Electrode

1. Product Overview

The Youveim® E150 NiFe-LDH@Nickel Fiber Paper Electrode is a pre-fabricated, high-activity alkaline oxygen evolution reaction (OER) electrode. It is manufactured by directly spraying Accelerate® NiFe-LDH nanosheets onto high-purity nickel fiber paper (also known as nickel felt).
This electrode combines excellent electrical conductivity, mechanical flexibility, and electrochemical stability, making it highly suitable for alkaline membrane electrode assemblies (AEMs) as well as liquid-phase electrolysis systems.

The NiFe-LDH active phase possesses a layered double hydroxide structure, which generates NiOOH–FeOOH active species under alkaline conditions—recognized as one of the most efficient catalysts for OER.

3. Recommended Usage (in Membrane Electrode Assembly Systems)

(1) Pre-treatment before Assembly

• Do not use ultrasonic cleaning.
  The electrode adopts a sprayed composite structure; ultrasonic vibration will cause delamination or catalyst loss.

• Surface dust removal:
  Blow the electrode surface gently with nitrogen or clean dry air to remove any debris.

• Alcohol wetting (optional):
  If the surface is hydrophobic, drop a small amount of ethanol or isopropanol to ensure uniform wetting for better contact with the membrane.

(2) Electrode–Membrane Assembly

• Recommended for use with alkaline anion exchange membranes (AEMs) such as PiperION, Sustainion, or A201.

• Place the active layer facing the membrane. For bipolar configurations, assemble both anode and cathode simultaneously.

• Use thermal pressing or mechanical compression for MEA fabrication.
  Recommended conditions:

  • Pressure: 0.5–1.0 MPa

  • Temperature: 60–80 °C

  • Time: 3–5 min

(3) Electrochemical Activation

Before formal testing, activate the electrode to stabilize the electrochemical interface:

1. Immerse the electrode in 1 M KOH for 10–20 minutes.

2. Conduct pre-treatment via cyclic voltammetry (CV) or galvanostatic activation:

   • Potential range: 1.0–1.6 V vs. RHE

   • Scan rate: 5 mV·s⁻¹

   • Cycle 10–20 times until the current response stabilizes.

3. After activation, proceed with constant-current or constant-potential measurements.

4. Key Features

• Superior Conductivity:
  3D nickel fiber paper provides rapid electron transfer and efficient gas release pathways.

• High Catalytic Activity:
  Layered NiFe-LDH promotes OH⁻ adsorption and oxygen evolution kinetics.

• Strong Adhesion:
  Proprietary spraying process ensures robust bonding between catalyst layer and substrate.

• Customizable Design:
  Catalyst loading, binder type, substrate, and dimensions can be tailored to research requirements.

5. Frequently Asked Questions (FAQ)

Q1: Can the electrode be ultrasonically cleaned?
A: No. Ultrasonic treatment damages the sprayed catalyst layer. Use dry air or gentle wiping for cleaning.

Q2: Is annealing required?
A: No. The E150 series is a ready-to-use electrode. For structural modifications, please contact us for custom versions.

Q3: Can it be used directly in an alkaline electrolyzer?
A: Yes. Recommended electrolyte: 0.5–1 M KOH at 25–60 °C.

Q4: Is it compatible with AEM water electrolysis?
A: Fully compatible. For optimal performance, pair with PiperION or Sustainion membranes.

Q5: How should the electrode be stored?
A: Keep unused electrodes in a dry, sealed bag. After use, rinse gently with deionized water and air dry naturally.

6. Typical Applications

• Anode for Alkaline Water Electrolysis (AEMWE)

• Oxygen Evolution Reaction (OER) electrocatalysis studies

• Development of renewable energy electrode materials

• Long-term stability evaluation under high-temperature or high-alkaline conditions
