Decomposition of copper(II), nickel(II) and cobalt(II) formates in self-generated atmospheres

Low Temperature Thermal Atomic Layer Deposition of Cobalt Metal Films

“…Treatment of 1 with formic acid in THF for 1 h at 66 °C led to a pink precipitate that was a mixture of cobalt(II) formate dihydrate, cobalt metal, CoO, and Co 3 O 4 by powder X-ray diffraction, 39 suggesting a complex reaction process. Bulk cobalt(II) formate undergoes selfdecomposition at 237 °C, 41 and should thus be thermally stable at <200 °C if it is formed as an intermediate species. Deposition data demonstrate that there is a small (10−15%) CVD component to the growth at 180 °C on ruthenium and also a nucleation period of ≤150 cycles on ruthenium before normal ALD growth ensues.…”

Evaluation of Co/SSZ‐13 Zeolite Catalysts Prepared by Solid‐Phase Reaction for NO‐SCR by Methane

“…The DTG curve measured on the Co(HCOO) 2 • 2H 2 O/NH 4 -SSZ-13 mixture shows two main peaks at around 90°C and 150°C ( Figure 1A, f), which can be assigned to water desorbing from the zeolite and to the loss of crystalline water from the Coprecursor salt ( Figure S6). [15,23] Note that we could not detect either HCOOH (or its decomposition products) or NH 3 , expected to be formed at low temperature. The appearance of a sharp peak at 283°C ( Figure 1A and 1B, f) indicates a fast decomposition process, in which CO, CO 2 , and water were released into the gas phase ( Figure S6).…”

“…The appearance of a sharp peak at 283°C ( Figure 1A and 1B, f) indicates a fast decomposition process, in which CO, CO 2 , and water were released into the gas phase ( Figure S6). Considering the characteristic peak temperature and the products formed, this process can be identified as the thermal decomposition of the dehydrated Co (HCOO) 2 precursor salt [23,24] giving Co/CoO as final products. These results suggest, that Co(HCOO) 2 in its dehydrated form could not move into the zeolite pores in an amount, to obtain significant degree of SSIE.…”

Synthesis and Electrochemical Behavior of Nanostructured Copper Particles on Graphite for Application in Lithium Ion Batteries

“…Therefore, our aim is to develop an environmentally friendly, simple and low cost procedure to deposit pure metal coatings on inorganic substances. It is well known that some metal formates sublimate and decompose at relatively low temperatures [24]. The exact chemical composition of the decomposition products is still not confirmed and varies for each metal formate.…”
