Laser Engineered Fabrication of Binder-Free NiCoFeCrZn-based High Entropy Oxide Electrode for Hydrogen Evolution Reaction in Alkaline Water

Key Points

• The aim is to synthesize a binder-free NiCoFeCrZn-based high entropy oxide for improving hydrogen evolution reactions.
• Utilized one-step CO2 laser irradiation on metal salts for synthesis.
• Fabricated the high entropy oxide directly over carbon cloth.
• The binder-free HEO-based electrode shows excellent activity for hydrogen evolution.
• Demonstrated effectiveness in alkaline water conditions.
