Graphene-based nanomaterials have attracted remarkable attention during the last decade in nanotechnology. In this review, we discuss the hybrid nanomaterials based on graphene oxide (GO) and nanoparticles (NPs). We review the synthesis, properties, and applications of immobilized transition metal oxide ...
Furthermore, the attachment of oxygen functional groups at its basal and edge planes of graphene has allowed for easy metal/oxide functionalization for improved properties harvesting. Fe2O3 nanoparticles (NPs) on the other hand have polymorphic property enabling the degeneracy of Fe2O3 in different...
Functionalized graphene oxide (GO)/SiO2nanocomposites (FGS) was successfully fabricated by two steps; the first one was the combustion of RHP in covered crucible inside stainless steel autoclave at three different temperature, 400, 500, and 600 °C at 1 h for obtaining ash RHA1, RHA2, and ...
This work reports the low-cost exfoliation of graphene oxide (GO) from pencil lead using modified Hummer's method. The gold nanoparticles (AuNPs) supported on GO is prepared via an in situ bio reduction of HAuCl4 by polyphenolic biomolecules present in young leaves of tea (Camellia sinensis) ...
We report a simple new approach for green preparation of gallic acid supported reduced graphene oxide encapsulated gold nanoparticles (GA-RGO/AuNPs) via one-pot hydrothermal method. The as-prepared composites were successfully characterized by using Four
The PDDA-rGO nanosheets could be modified with Ag nanoparticles (AgNPs) by direct adsorption of preformed, negatively charged AgNPs. It was found that the AgNPs were distributed uniformly on the PDDA-rGO nanosheets and the obtained PDDA-rGO/AgNPs nanocomposites exhibited prominent electrocatalytic ...
The graphene/GO provides support for metal oxides, preventing the agglomeration of nanoparticles (NPs) and volume change during cycling [35], [57]. A few review articles focused on the electrochemical energy storage applications of graphene materials have been published, discussing recent outcomes and...
This review focuses on the recent advances in the synthesis of graphene quantum dots (GQDs) and their applications in drug delivery. To give a brief understanding about the preparation of GQDs, recent advances in methods of GQDs synthesis are first prese
CuCr2O4 nanoparticles implanted on graphene Oxide in nanocomposites CuCr2O4/GO were produced as an efficient energy storage material using the co-precipitation method [18]. Various methods for preparation of graphene oxide have been developed, which could be separated into two categories: chemical ...
The limited dispersion stability of graphene in lubricating oils and the high cost of chemical deposition method to prepare SiO2/GO composite materials. Th
