Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: Medium

The porous, mechanically stable, thermally coupled HKUST-1 coatings are positioned for heat exchangers in sorption heat pumps, catalysis and gas storage.

Caveat: No device-level heat-pump or catalysis performance test is reported in this paper.

9710 · Summary · Linked to 4 structured results

CaveatSupport assessment: High

Water-vapour cycling destroys the HKUST-1 crystal structure while leaving mechanical adhesion unchanged.

Caveat: Cycling conditions are severe and described specifically in the SI.

9710 · Results · Figure S7 · Linked to 3 structured results

Phase AssignmentSupport assessment: High

The thicker top layer of the coating consists of HKUST-1 and the coating PXRD confirms HKUST-1 as the major crystalline phase.

Caveat: The complete coating also includes a carbon-rich bottom interlayer with non-HKUST-1 phases.

Structure Property LinkSupport assessment: Medium

High thermal conductivity is attributed to highly intergrown crystallites that facilitate heat transfer compared with loose particle or bead packings.

Caveat: Thermal analysis averages top and bottom coating layers and relies on assumed density and Basolite-derived heat capacity.

Synthesis MechanismSupport assessment: Medium

The bottom layer is likely a mostly organic, polymeric carbon-rich material formed under copper-catalysed conditions, with Cu2O/rouaite also present.

Caveat: Authors explicitly state the organic phase is apparently amorphous and only anticipate a mostly organic/polymeric structure.

Synthesis MechanismSupport assessment: Medium

The substrate itself plays a minor role as a metal source under the applied conditions because HKUST-1 layer formation was observed on copper, aluminium and stainless steel sheets.

Caveat: Detailed recipes and measurements for aluminium and stainless-steel coatings are not provided.
