Abstract

A novel, mesoporous molybdenum doped titanium dioxide-reduced graphene oxide composite is synthesized as a highly efficient heterogeneous solid acid catalyst.

Graphene oxide:Fe2O3 nanocomposites for photodetector applications: experimental and ab initio density functional theory study

“…2(e) and (f) shows the particle size distribution and EDX spectra analysis of GO:Fe 2 O 3 nanocomposite from TEM measurements. The distribution indicates most of the particle sizes were in the range 80–100 nm, which suggests a monomodal particle size distribution 24 and are in proximity of the crystallite size (see Table 1 ), which was obtained from XRD. The EDX spectra on the other hand show the presence of C, O and Fe in the sample as expected.…”

TiO2-Coated MoO3 Nanorods for Lithium/Sodium-Ion Storage

“…Both the cathodic peak in a vicinity of 1.75 V and the anodic peak close to 2.1 V are noticeable in all CV curves, representing the Li intercalation/deintercalation process at the MoO 3 @TiO 2 -2 electrode. 54,55 The following CV curves exhibit a strong concurrence, indicating stable surface conditions and Electrospray impedance spectroscopy (EIS) assessments were accomplished to comprehend the kinetic mechanism and electrode conductivity (Figure 5b). All of the obtained EIS curves expose a diminished semicircular arc within the region of high to medium frequencies alongside a gradually sloping straight line in the low-frequency range.…”

Graphene oxide-supported nickel(ii) complex as a reusable nano catalyst for the synthesis of bis(indolyl)methanes

“…The Raman spectrum of GO shows two typical characteristic bands, the D band (1348 cm −1 ) and the G band (1594 cm −1 ). 28 The value of the I D /I G ratio of GO (0.956) changes to 1.003 after APH tagging and 1.32 after complexation with Ni(II), suggesting an increased disturbance in the GO lattice structure after the tagging of APH and the complexation process. Hence, this confirms the successful grafting of the APH-Ni(II) complex on GO sheets.…”
