“…All the identified absorption bands are summarized in Table 1. Similar characteristic absorption bands were also observed during the thermal decomposition of Y(CF3COO)3 [17] and Cu(CF3COO)2 [10]. CF3COOH or CHF3.…”

“…The manufacture of HTS coated conductors beneficiates from a prior knowledge of the (metal) TFA thermal decomposition mechanism, by allowing the determination and optimization of the involved pyrolysis and reaction processes. Therefore, an increasing number of studies on the thermal decomposition of TFA complexes have been made in the past years [8]- [10]. Earlier, Rillings had investigated the thermal decomposition of the Pr, Sm and Er trifluoroacetate compounds in air and vacuum, wherever the formation of LnF3 and LnOF (Ln=Pr,Sm and Er) was ascertained [11].…”

Anhydrous nanoscopic CuF is synthesized from alkoxides Cu(OR) (R=Me, tBu) by their reaction either in pure liquid HF at -70 °C, or under solvothermal conditions at 150 °C using excess HF and THF as solvent. Depending on the synthesis method, nanoparticles of sizes between 10 and 100 nm are obtained. The compound is highly hygroscopic and forms different hydrolysis products under moist air, namely CuF ⋅2 H O, Cu (OH)F , and Cu(OH)F, of which only the latter is stable at room temperature. CuF exhibits an electrochemical plateau at a potential of ≈2.7 V when cycled versus Li in half cell Li-ion batteries, which is attributed to a non-reversible conversion mechanism. The cell capacity in the first cycle depends on the particle size, being 468 mAh g for ≈8 nm crystallite diameter, and 353 mAh g for ≈12 nm crystallite diameter, referred to CuF . However, such a high capacity cannot be sustained for several cycles and the capacity rapidly fades out. The cell voltage decreases to ≈2.0 V for CuF ⋅2 H O, Cu (OH)F , and Cu(OH)F. As all the compounds studied in this work show irreversible conversion reactions, it can be concluded that copper-based fluorides are unsuitable for Li-ion battery applications.

“…In this context, the thermolysis of copper(II) trifluoroacetate should occur below the decomposition temperature of copper nitride. 32 Second, use of soluble salts offers the opportunity for facile, inexpensive solution-based methods to deposit precursor films for subsequent solid-vapour reactions. Hence, in this article, we report how copper(II) trifluoroacetate can be exploited to produce both powder and thin film samples of copper nitride.…”
