A new route to copper nitrate hydroxide microcrystals

Synthesis of CuO@NiO core-shell nanoparticles by homogeneous precipitation method

“…The band at 638 cm À1 is due to Ni-O-H bending and the band at 475 cm À1 is due to Ni-O stretching [64,65]. Free nitrate ion shows two active vibration modes, where as the nitrate ion present in the interlayers shows four vibrational modes [66]. These four vibrations have been observed in the IR spectrum of CuO precursor; the peak at 1043 cm À1 , one singlet at 875 cm À1 , doublet at 1418 and 1340 cm À1 and another doublet at 750 and 700 cm À1 [67].…”

Visible‐Light‐Induced Dye Degradation over Copper‐Modified Reduced Graphene Oxide

“…The well-resolved peaks can be indexed to (001), (002), (120) [41,42] Compared to the Cu precursors added to RGO suspensions, the deposited Cu 2 + salts apparently underwent slight hydrolysis after being immobilized on the RGO surface. The sharp peaks in the XRD patterns suggest high crystallization of the loaded Cu species.…”

Large pore volume mesoporous copper particles and scaffold microporous carbon material obtained from an inorganic–organic nanohybrid material, copper-succinate-layered hydroxide

“…In each layer, one-fourth of the hydroxide ions are substituted by nitrate anions that are positioned between the layers and are coordinated with copper cations via one oxygen atom. This decreases the basal spacing to around 6.9 Å compared to that of other single metal layered hydroxides with the same interlayer anion such as zinc hydroxide nitrate with 9.7 Å basal spacing [1][2][3][4][5][6]. In zinc hydroxide nitrate, nitrate anions together with water molecules are free between the layers and are not coordinated to the layers.…”
