Synthesis and characterization of conductive copper-based metal-organic framework/graphene-like composites

• A new class of HKUST-1/graphene-like composites was produced.
• High amount of graphene-like does not interfere with the HKUST-1 crystal growing.
• Composites exhibit a new porosity.
• Strong increase of the dc conductivity as a function of graphene-like content.

Metal-organic framework (MOF) incorporating conductive graphene-like layers were synthesized and characterized. The selected MOF, HKUST-1, combines high surface area, water stability, simple preparation and low costs. Graphene-like layers incorporated into the MOF structure were obtained by a two-step oxidation/reduction wet treatment of a high surface carbon black. MOF composites were produced at different carbonaceous layers content. It was shown, through a wide characterization of the samples, that the composites preserve the main features of the parent MOF, additional exhibiting a tunable electrical conductivity.
