A novel class of zinc - doped HKUST-1 samples was synthesized and structurally characterized with the aim of understanding the effect of metal substitution on the chemico-physical properties of the copper-based metal organic framework (MOF) HKUST-1. The samples were produced by varying the Zn2+ loading in the framework from 0.2 wt.% up to 30 wt.%. Also a combined introduction of electrical conductive graphene-like (GL) layers and Zn2+ ions aimed to the production of zinc doped HKUST-1/GL composites was explored. The materials were characterized by XRD and FTIR spectroscopies, TGA, SEM, BET specific surface area and elemental analysis. It was shown that the incorporation of GL up to 15% and Zn2+ up to 50% does not affect drastically the structural features (crystal shape, microporosity, thermal behavior) of HKUST-1 phase.

Abstract
A novel class of zinc - doped HKUST-1 samples was synthesized and structurally characterized with the aim of understanding the effect of metal substitution on the chemico-physical properties of the copper-based metal organic framework (MOF) HKUST-1. The samples were produced by varying the Zn2+ loading in the framework from 0.2 wt.% up to 30 wt.%. Also a combined introduction of electrical conductive graphene-like (GL) layers and Zn2+ ions aimed to the production of zinc doped HKUST-1/GL composites was explored. The materials were characterized by XRD and FTIR spectroscopies, TGA, SEM, BET specific surface area and elemental analysis. It was shown that the incorporation of GL up to 15% and Zn2+ up to 50% does not affect drastically the structural features (crystal shape, microporosity, thermal behavior) of HKUST-1 phase.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
