OBTAINING OF NANODIMENSIONAL POWDERS BY METHOD OF HYDROTHERMAL DECOMPOSITION OF Cu, Co, AND Al NITRATES IN POLYOLIC ENVIRONMENT
Journal Title: Azerbaijan Chemical Journal - Year 2018, Vol 0, Issue 2
Abstract
The hydrothermal reductive decomposition of Cu2+, Co2+ and Al3+ nitrates in the temperature range of 220–350oС in the presence of polyols (ethylene glycol and glycerol) was investigated. It has been established, that depending on the synthesis conditions the forming of highly dispersed oxide systems of Cu–Co–Al and/or with admixture of metallic copper are possible. The products of reaction by physicochemical methods: XRF, SEM, spectroscopy in the IR and UV ranges are characterized. A correlation between the reaction conditions and the physical and chemical properties of the nanopowders was established. A possible scheme for the flow of reaction is proposed
