Author InterpretationHigh supportMaterial Comparison
2D c-MOF analogues are presented as favourable for electrocatalysis because exfoliated layers expose more active sites, shorten diffusion paths, support delocalised in-plane transport and form better electrode films.
Evidence basis: multi_reference
Caveat: The review does not claim all 2D MOFs outperform all 3D MOFs; it frames a general advantage set.

Bimetallic incorporation in c-MOFs is framed as a route to tune d-band centres, adsorption energies, charge transfer and bifunctional HER/OER activity.
Evidence basis: multi_reference
Caveat: The introduction notes instability as a major drawback of multi-metallic MOFs, so performance and durability must be separated.

Extended p-d conjugation produces graphene-like delocalisation in 2D c-MOF layers and is central to many electrocatalytic examples.
Evidence basis: multi_reference
Caveat: Layer stacking, defects and measurement geometry still influence observed conductivity.

The review adopts five design pathways for conductive MOFs: through-bond, extended conjugation, through-space, redox hopping and guest-promoted transport.
Evidence basis: multi_reference
Caveat: The five-way taxonomy is a useful review framework, not a claim that mechanisms are always separable in real electrodes.

Guest species can extrinsically enhance conductivity and catalysis by adding charge carriers, donor-acceptor interactions or additional conductive pathways.

Caveat: Guest incorporation may affect morphology, stability and selectivity in different directions depending on host-guest chemistry.

Consensus SummaryHigh supportCaveat
Conventional insulating MOFs have attractive porosity and tunability but often fail in electrocatalysis because weak coordination bonds and poor electronic conductivity limit stability and charge transfer.
Evidence basis: multi_reference
Caveat: The review summarises multiple sources and does not provide new measurements.

Author InterpretationHigh supportTransport Mechanism
Efficient electrolysis requires both electronic conduction through the catalyst/electrode and ionic conduction in the electrolyte to maintain charge neutrality and deliver reactants.
Evidence basis: review_reasoning
Caveat: The review frames this generally rather than resolving measurement protocols for mixed conduction.

In situ and operando measurements are needed to identify intermediates, monitor reconstruction and interpret catalytic mechanisms in unstable aqueous c-MOF electrodes.

Metal-node identity and ligand donor atoms influence conductivity through orbital overlap, band alignment and electronic configuration.

The review repeatedly cautions that c-MOF electrocatalysts remain below practical industrial requirements for current density and long-term durability.

Redox hopping differs from band-like transport because charges are localised and hop between redox-active moieties; temperature, porosity and ion diffusion can control performance.
Evidence basis: multi_reference
Caveat: The review states that thoroughly evaluating redox-hopping mechanisms remains difficult.

Through-space stacking can enhance electron mobility, but excessive pi-pi stacking can hide active sites and reduce electrocatalytic performance.
