Efficient NiFeCr0.1/NF by incorporating chromium to boost OER catalysis

High Entropy Spinel Oxide (AlCrCoNiFe2)O as Highly Active Oxygen Evolution Reaction Catalysts

“…Of particular interest is the significant decrease in overpotential observed upon the addition of Cr into (AlCoNiFe 2 )­O, resulting in a reduction of approximately 100 mV. This notable enhancement can be attributed to the high entropy effect induced by the addition of Cr, which introduces increased disorder and complexity into the material’s structure, thereby facilitating more efficient OER catalysis. , …”
