A convenient alcohothermal approach for low temperature synthesis of CuO nanoparticles

Solar absorptance of copper–cobalt oxide thin film coatings with nano-size, grain-like morphology: Optimization and synchrotron radiation XPS studies

“…It is widely known that the increase in temperature changes the characteristic of oxidation states of a surface. In relatively low temperatures (under 150 o C), the copper oxide obtained from alcohothermal process of copper acetate precursor undergoes a binding energy shifting of Cu 2+ oxidation state from A-sites (tetrahedral coordination) toward to B-sites (octahedral coordination) as temperatures are increased [33,37]. However, in this temperatures range, no reduction of Cu 2+ occurred [37].…”

Enhanced Raman Scattering as a Probe for 4-Mercaptopyridine Surface-modified Copper Oxide Nanocrystals

“…The existence of such a strong satellite feature for Cu 2p rules out the possibility of the presence of Cu2O phase. 30 The peak at 952.9 eV is attributed to Cu 2p1/2. The gap between the Cu 2p1/2 and Cu 2p3/2 levels is about 20 eV.…”

Microemulsion Synthesis of Copper Oxide Nanorod-Like Structures

“…To investigate for those effects and for possible applications, nanostructured copper oxides have been synthesised in several shapes such as 3 nanobelts [25], nanorods [26], nanowires [27], and nanoribbons [28]. Several techniques, ranging from reverse micelles microemulsions [29], electrochemical and sonochemical deposition [30,31], chemical vapour deposition [32], alcoho-thermal and hydrothermal synthesis [33,34], thermal decomposition [35] and high-temperature synthesis [36] are available to produce such non-equilibrium morphologies.…”
