Metal Acetylene Dicarboxlylates as Catalyst for Printable Low Temperature Carbon Precursors

Abstract

The synthesis of various metal acetylene dicarboxylates (MxADC, M = Cu, Ag, Fe, Co, Ni) via new methods are reported. The previously unknown crystal structures for Ag2ADC and FeADC are presented. The behaviour of the different metal dicarboxylates and their role as graphitization catalysts in a printable highly energetic carbon precursor is investigated in detail. Despite the copper compound has the lowest decomposition temperature of all studied acetylene dicarboxylates and is significantly enhancing the conductivity of carbon thin films obtained at low pyrolysis temperatures, the catalytic effect of cobalt and iron on graphitizing carbon results in a superior conductivity in carbon thin films pyrolyzed at lower temperatures down to 600°C. The newly designed precursors are demonstrated to produce micro‐supercapacitors with a 3D‐piezoelectric inkjet technique at low pyrolysis temperature.
