Recent progress on graphene/nanostructured oxide composites as advanced multifunctional nanonetwork is described, highlighting the importance of the interactions between graphene and the nanostructured materials and the beneficial role of graphene in their based composites for specific applications. In this ...
举例:In order to obtain better confirmation on the presence of H4SiMo12O40, Raman spectroscopic investigation was also conducted, because Raman spectroscopy is a sensitive technique to study supported metal oxide and it is complementary to IR investigation. The Raman spectra of the MoVI@mSiO2 and ...
The agglomeration of graphene sheets is also confirmed with Raman spectroscopy as shown inFig. 4.The D band of our sample is relatively intense compared to the G band, which is in agreement withprevious results for graphene samples obtained from exfoliated GO. It was shown that alongthe graphit...
Graphene oxide (GO) is a promising material for energy storage device applications. Modified Hummers method (MHM) has been used to prepare GO films from graphite flakes by Sol-Gel method. With the aid of bridging agent dimethyldichlorosiline, structurally fine GO films were prepared. Fourier tran...
(blue-shift),and the D band grew in intensity. The Raman spectrum of our sample contains a G band at 1584 cm-1, a D band at 1352 cm-1 and the second-order features, at 2690 and 2910 cm-1.The G band position (1584cm-1) of our reduced graphene oxide powder sample is in good ...
Electronic Transport Properties of Individual Chemically Reduced Graphene Oxide Sheets Individual graphene oxide sheets subjected to chemical reduction were electrically characterized as a function of temperature and external electric fields...

This chapter is a review of the application of Raman spectroscopy in characterizing the properties of graphene, both exfoliated and synthesized, and graphene-based materials such as graphene-oxide. Graphene is a 2-dimensional honeycomb lattice of sp2-bonded carbon atoms and has received enormous inter...
