One-Step In situ Synthesis of SnO₂/Graphene Nanocomposites and Its Application As an Anode Material for Li-Ion Batteries

Abstract

A facile one-step solution-based process to in situ synthesize SnO(2)/graphene (SG) nanocomposites was developed, by using the mixture of dimethyl sulfoxide (DMSO) and H(2)O as both solvent and reactant. The reduction of graphene oxide (GO) and the in situ formation of SnO(2) nanoparticles were realized in one step. The electrochemical experiments showed the composites provided a better Li-storage performance. The method presented in this paper may provide an effective, economic, and green strategy for the preparation of metal-oxide/graphene nanocomposites.

Photocatalytic degradation of acetic acid in the presence of visible light-active TiO 2 -reduced graphene oxide photocatalysts

“…In recent years, graphene, a two-dimensional novel carbon nanomaterial with zero band gap, large specific surface area, excellent mechanical, electrical, optical and thermal properties and its applications in sensors and biosensors, electronic devices, liquid crystalline displays, capacitors solar cells, H 2 production, energy storage and nanocomposites including TiO 2 /graphene materials, has been intensively studied [1][2][3][4][5][6][7][8][9][10]. Graphene is composed of single or less than 10 planar sheets of sp 2 -bonded carbon atoms forming six-membered rings [11].…”

Carbon quantum dots/SnO2–Co3O4 composite for highly efficient electrochemical water oxidation

“…The composites based on metal oxide and SnO 2 can efficiently improve the electronic conductivity property [17]. Nevertheless, the poor cyclic stability in alkaline medium is a tricky problem for their further applications [18][19][20]. Carbon quantum dots (CQDs), as a novel class of nanocarbon, show small particle size ($5 nm), supernal conductivity, rapid electron transfer and electron reservoir properties [21][22][23][24].…”

Graphene nanosheets@ZnO nanorods as three-dimensional high efficient counter electrodes for dye sensitized solar cells

“…Recently, a general strategy-jamming GNs with metal oxide SnO 2 nanoparticles has been developed to minimize the aggregation of graphene for lithium-ion batteries. 22 The introduction of SnO 2 nanoparticles into the dispersion of GNs impedes the formation of a stacked graphitic structure. Therefore, the hybrid SnO 2 -graphene should not only reduce the degree of stacking of GNs, but also boost the lithium storage capacity.…”
