Key Points

The aim is to enhance the performance of nickel-based catalysts for HMF electro-oxidation by incorporating palladium.
Synthesize NiCo-MOF/Ni-foam catalysts with varying Pd incorporation levels.
Test the electro-oxidation activity of these catalysts on 5-hydroxymethylfurfural.
Evaluate the selectivity for 2,5-furandicarboxylic acid and co-production of green hydrogen.
Catalysts with high-valent Ni<sup>3+</sup> active sites showed significantly higher electro-oxidation activity.
An optimal palladium incorporation level resulted in the best selectivity for FDCA.
The catalysts maintained low costs while achieving high activity, supporting green hydrogen production.

Implication

Demonstrates enhanced electro-oxidation of HMF in nickel-based catalysts, indicating improved green hydrogen production efficiency.

Abstract

Electro-oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) enables the co-production of green hydrogen under ambient conditions, yet anode catalysts must simultaneously deliver high activity, selectivity, and low cost. Nickel-based...
