Controlled morphologies of copper oxide single crystalline nanostructures by wet chemistry and thermal decomposition processes

Nanowires-assembled CuO Interpenetrated-leaf Architecture by () Twinning

“…The surface of the leaf is (001), the plane with the lowest surface energy. These observations present a crystal orientation dependence of growth rate order: 010 > 100 > 001, which is consistent with previous results [8][9][10].…”

“…For example, the CuO monoclinic structure is anisotropic with respect to the surface energy. The (001) plane with the maximum atomic number density has the lowest surface energy and is consequently easy to form, whereas the (010) plane with the lowest surface atomic number and highest surface energy is the most unstable [8][9][10]. Because of this anisotropy, various CuO nanostructures were grown [10][11][12].…”

Pseudocapacitive performance of vertical copper oxide nanoflakes

“…In addition to the Cu 2p 3/2 and 2p 1/2 peaks, typical CuO-satellite peaks appear at binding energies of 943.8 and 963.7 eV, and the existence of a strong satellite pattern for the Cu 2p rules out the possibility of the presence of Cu 2 O phase. Since the 3d shell is expected to be completely filled in Cu 2 O, the shake up satellite peaks indicate the presence of an unfilled Cu 3d9 shell, that is, the existence of CuO at the surface [21,22]. It has been also reported that Cu 2 O can be easily covered by a relatively more stable CuO surface layer [24].…”

Tuning Dimensionality of Benzimidazole Aggregates by Using Tetraoctylammonium Bromide: Enhanced Electrochemiluminescence Studies

“…21−25 However, using TOAB to synthesize 2D lamellar materials has not been sufficiently studied. 26 In this work, utilizing the nature that lipophilic BIM tends to be adsorbed on the hydrophobic chains of TOAB, 2D lamellar layer materials (BIM/TOAB) have been constructed (Scheme 1). By adjusting the ratio of TOAB to BIM, the optimal amount of BIM load on TOAB has been explored.…”

“…Therefore, TOAB tends to assemble into 2D lamellae during recrystallization in water, which is a suitable template to tune the dimensionality of BIM. TOAB has been widely used as a phase transfer agent in the synthesis of gold nanoparticles and as a surfactant to adjust the nanoparticle morphology. − However, using TOAB to synthesize 2D lamellar materials has not been sufficiently studied . In this work, utilizing the nature that lipophilic BIM tends to be adsorbed on the hydrophobic chains of TOAB, 2D lamellar layer materials (BIM/TOAB) have been constructed (Scheme ).…”
