High-Entropy Metal-Organic Framework Arrays Boost Oxygen Evolution Electrocatalysis

The quintuple-metal HE-MOF array gives the best OER activity in the reported sample set, with eta50 = 254 mV and a 61 mV dec-1 Tafel slope.

Caveat: Performance is application-specific OER activity, not a direct electrical conductivity measurement.

The HE-MOF is a 2D mixed-metal MOF composed of alternating 2,6-naphthalenedicarboxylate hydrocarbon layers and inorganic MO6 metal-oxygen layers.

Caveat: No CIF is provided in the assignment; structure description is taken from the article's literature-matched XRD/FT-IR/XPS interpretation.

Hierarchical porosity and open 2D nanosheet arrays are claimed to aid electrolyte/gas mass transport and reduce O2 bubble accumulation.

Caveat: Mass-transport benefit is inferred from morphology, porosity and OER behaviour.

MO6/MOOH intermediates are proposed as active centers during OER over the HE-MOF.

Caveat: Mechanistic assignment is based on CV feature interpretation and literature reasoning rather than direct operando structural proof in the extracted text.

The 2D vertically aligned HE-MOF array is claimed to enhance electrical conductivity and promote reactant, intermediate and product mass transfer.

Caveat: The paper reports EIS and OER performance but no direct intrinsic electronic conductivity value.
