Boron-Induced Cationic Vacancy on Copper Cobalt Oxide toward Formate Selectivity: New Insights into Methanol Oxidation Reaction

“…It is noteworthy to mention that the peak intensity of the 222 plane was drastically reduced after the incorporation of boron. As per the literature, the peak observed at the 222 plane corresponds to Co 2 O 4 . , Interestingly, the reduction in peak intensity might be due to the formation of cationic vacancy. In line with XRD spectra, Fourier transform infrared (FTIR) spectra were recorded and are exhibited in Figure S1.…”

Magnetic Hyperthermia and Antibacterial Response of CuCo2O4 Nanoparticles Synthesized through Laser Ablation of Bulk Alloy

“…XRD characteristic diffraction peaks with minor differences, such as 38.3, 44.6, and 65.1°, corresponding to (222), (400), and (440) for CuCo2O4 particles have been reported in [57]. Diffraction peaks for CuCo2O4 nanoparticles have been found at 38.6, 44.8, and 65.2°, and they belong to (222), (400), and (440) planes, respectively [58][59][60].…”

Playing on 3D spatial distribution of Cu-Co (oxide) nanoparticles in inorganic mesoporous sieves: Impact on catalytic performance toward the cinnamaldehyde hydrogenation

“…Regarding the literature, Cu and Co bi-metallic materials were deposited onto various supports such: SiO2 [17][18], Al2O3 [19] TiO2 [20][21] porous carbon [22], etc. In an attempt to summarize the above observations, three situations can be found on solids based on Cu-Co supported on silica: formation of single monometallic oxides of i) large CuO NPs; ii) the spinel Co 2+ 1Co 3+ 2O4 NPS or iii) combination of both Co and Cu within the bimetallic spinel, with general formula CuxCo(3-x)O4 [23][24][25]. The Co3O4 spinel belonging to the space group Fd3m has oneeighth of the tetrahedral sites occupied by Co 2+ cations, while one half of the octahedral sites are occupied by Co 3+ cations, consequently, the insertion of Cu 2+ within the spinel will take place in the tetrahedral position of Co 2+ as follow CuxCo(1-x)Co2O4, where x can have only values inferior to 1.…”
