“…A representative example of layers exclusively formed by cations octahedrally coordinated by hydroxyl groups and functionalized with nitrate ions is found in a copper hydroxide nitrate reported by Aguirre et al [69]. In this case, the functionalization by nitrate ions is clearly determined by infrared spectroscopy, where the nitrate ions presented two intense bands at 1426 and 1343 cm −1 corresponding to asymmetric and symmetric stretching, respectively, of nitrate anions coordinating some copper cations [69].…”

“…Commonly, an LDH with free nitrate ions presents basal spaces between 8 and 9 Å. If nitrate ions functionalize the hydroxylated layers, the basal space decreases to 6 Å as presented in Figure 8 [69].…”

Layered double hydroxides (LDH) and layered hydroxide salts (LHS) are widely studied as matrices to design new materials with applications in several areas of science and technology. Both LDH and LHS are composed of molecular layered units with surfaces fully covered by hydroxyl groups and positive-charge residues within the layers; therefore, anions in the interlayer space are needed. Even though these anions are described as interlayer species without a covalent interaction with the molecular layered units, the substitution of hydroxyl groups is also possible; in other words, the functionalization of the surface could occur. This chapter reviews results previously published related to the functionalization phenomenon in LDH and LHS, which is not considered in most of the scientific reports of new materials derived from these compounds. In this text, the use of copper probes to study electron paramagnetic resonance spectra, reinforced with infrared spectroscopy to confirm functionalization, is described. The occurrence of functionalization instead of a simple anion exchange provides a change of properties in the final nanosized material.

“…X-ray diffraction analysis, TG and FTIR spectroscopy indicated the presence of Cu 2 (OH) 3 NO 3 in the precipitates. Cu 2 (OH) 3 NO 3 were obtained by adding aqueous sodium carbonate [8], aqueous ammonia [9] or solid Mg(OH) 2 [8] to aqueous copper nitrate solution. Neither copper carbonate [7] nor copper tetramine nitrate [9] were formed in these reactions.…”

Abstract:The present study attempts the preparation of copper borate as a lubricating oil additive by the reaction of copper nitrate and borax solutions. Effects of borax/ copper ratio, surface active agent (Span 60), pH, temperature and mixing time on properties of the products were investigated. The obtained products were not pure form; therefore they were analyzed in detail. They were characterized by color measurement, X-ray diffraction, SEM, zeta sizer, ICP, EDX, TG, DSC, CHNS analysis and FTIR spectroscopy.

or CO 3 − indicating the mineralization of DMCP to form CuCl 2 and CuCO 3 is shown. Even though more DMCP is reactively adsorbed on CuON, its decomposition is faster on CuONGO. Detected NO 2 , which is formed as an intermediate, causes the conversion of an unevaporated DMCP liquid to H 3 PO 4 , as supported by MS results. This mineralization of DMCP happens via an indirect contact with the catalyst. Thus, CuON and CuONGO are considered as highly powerful media for the decontamination of chlorophosphate-based nerve agents.
