We recently worked on the Raman Spectroscopy of Graphene Oxide (GO). Graphite was the starting material of our work which was oxidized according to Hummer's method. The observed peaks in the Raman spectrum are D-band at 1353cm-1, G-band at 1592cm-1 and 2D band at 2703cm-1. Raman ...
Graphene oxide is highly desired for printing electronics, catalysis, energy storage, separation membranes, biomedicine, and composites. However, the present synthesis methods depend on the reactions of graphite with mixed strong oxidants, which suffer f
Further observation for the morphology of graphene oxide/silica samples have been explored deeply by HR-TEM microscopy and the images are presented in Fig.5. As we know, the graphene was highly aggregated and presented a blocky structure15. In general, the sheet architecture is related to the ...

Graphene oxide (GO) was prepared according to the improved Hummers' method [58]. 2.4. Peroxidase-like activity of GNR Peroxidase-like activity of GNR in the presence of H2O2 and TMB was evaluated and compared with the catalytic activity of GO and MWCNT. To this aim, 100 μL of each ...
Crystalline graphitic layer intensity and disordered carbon peaks of AS/NZVI/GO were confirmed by Raman. Surface elemental compositions were determined using an ESCALAB 250Xi X-ray photoelectron spectroscopy (XPS) (Thermo Fisher Scientific, USA). The magnetic property of the adsorbent was analyzed by...
This work focused on the synthesis of 3D Pd-based nanocomposites which were tested in Heck coupling reactions and for the hydrogenation of nitroarenes. This was achieved by fabrication of graphene oxide/nitrogen-doped carbon nanotubes (G/N-CNTs) by mechanical grinding of 2D graphene oxide (GO)...
Hydrothermal reduction is a promising approach for graphene oxide (GO) reduction since it is environmentally friendly, simple, and cost effective. We present a detailed study of structural changes occurring in graphene oxide during the reduction process. The correlations between the interlayer spacing,...
The Raman Spectra of MoS and MoS-G were shown inFig. 1c. The three peaks in the lower wave number range (300–500 cm−1) correspond to hexagonal MoS2. The peak at 381 cm−1ascribed to E12g, associated with the opposite vibration of two S atoms with respect to Mo atom and...
