Zinc Oxide/Graphene Oxide Nanocomposites: Synthesis, Characterization and Their Optical Properties

Enhanced photocatalytic activity and diode performance of ZnO‐GO nanocomposites via doping with aluminum

“…All the peaks and their related origins are labeled on the figure. Peaks located at 335, 433, 576, and 1161 cm −1 were affiliated to ZnO 56 . The strong characteristic peak at 438 cm −1 is ascribed to the E 2 high‐frequency phonon mode of Zn verifying the successful preparation of hexagonal wurtzite ZnO 57 .…”

“…Peaks located at 335, 433, 576, and 1161 cm À1 were affiliated to ZnO. 56 The strong characteristic peak at 438 cm À1 is ascribed to the E 2 high-frequency phonon mode of Zn verifying the successful preparation of hexagonal wurtzite ZnO. 57 The slight shift toward lower wavenumber (red shift) corroborated the impact of defects arising from contraction in the crystallite domain, which is a further demonstration of the presence of Al in the ZnO matrix, 58 which leads to a reduction in grain size, as confirmed by the data of XRD, HRTEM, FESM.…”

Synthesis and characterization of MoxFe1−xO nanocomposites for the ultra-fast degradation of methylene blue via a Fenton-like process: a green approach

“…The calculated optical band gaps of the Mo x Fe 1− x O ( x = 0.05, 0.10, 0.15) nanocomposites match with those from some previously reported works. 52,53…”

“…The calculated optical band gaps of the Mo x Fe 1Àx O (x = 0.05, 0.10, 0.15) nanocomposites match with those from some previously reported works. 52,53 Fenton-like activity of the nanocatalyst found to be inconsistent with variations in the concentration of each of the produced nanocomposites, which will be explored further. When the Fenton catalyst was changed to a different proportion of Mo, the removal efficiency of MB was greatly enhanced at a certain percentage of Mo incorporation in the FeO matrix.…”

Poly(methyl methacrylate) and silica nanocomposites as new materials for polymeric optical devices

“…From another perspective, nanotechnology enables advances in the development of new, high-performance, innovative nanocomposite materials [14][15][16][17][18][19][20][21][22][23][24][25][26][27] , with unique properties deriving from a synergistic relationship between a polymer matrix and a nanometric filler [25][26][27] that depends on particles dimensions, chemical affinity between polymer and particles and their dispersion on a nanometric scale within the matrix [25][26][27] . New properties of nanocomposites, such as mechanical and thermal enhancements, electric conductivity and different chemical reactivity depend on the type of filler, and might not be observed with micrometric or macrometric particles [28][29][30][31][32][33][34][35][36][37][38][39] . Several studies on PMMA nanocomposites showed that their mechanical properties can be enhanced without impairing their remarkable optical properties [12,13,34] .…”
