A facile one-step hydrothermal method to produce graphene–MoO3 nanorod bundle composites

Ag/ZnO/graphene oxide heterostructure for the removal of rhodamine B by the synergistic adsorption–degradation effects

“…Graphite oxide was synthesized from natural graphite by a modified Hummers' method with additional KMnO 4 [33,34,44]. In a typical synthesis, zinc acetate dehydrate (10 mmol, 2.2 g) was reacted with potassium hydroxide (0.34 mol, 19.1 g) in methanol (100 mL) at 55 1C for 3 h; the resulting dispersion was thus aged in the mixed methanol/diethyl carbonate/chloroform solvents for 3 days.…”

“…The two mentioned impacts imply enhanced light absorption and improved degradation efficiency. Graphene oxide, an oxygen-containing derivative of graphene, has been used as a promising material for the fabrication of composite materials for potential applications in different fields [29][30][31][32][33][34], owing to its unique two-dimensional structure, solution processability and functionalization-induced tunable electronic structures. Moreover, negatively-charged GO sheets provide more active sites for the hybridization of functional materials and for the adsorption of dye molecules, enabling the controllable synthesis of well-defined GO-based functional composite materials.…”

Phase-tailored synthesis of tin oxide–graphene nanocomposites for anodes and their enhanced lithium-ion battery performance

“…After the first cycle, the SG-0.01 anode showed superior reversible performance, which retained a reversible capacity of 525 mAh g À 1 after 90 cycles. Note that the average capacity loss is only $0.3%, which is superior among those SnO 2 -graphene nanocomposites anodes in literatures [14][15][16]. The ultra-low capacity loss suggests that the SG-0.01 anode possesses an excellent cycling performance, which is attributed to the optimal buffering and conductive effects of graphene nanosheets [3].…”

“…In the near term, SnO 2 -graphene nanocomposites were synthesized by mechanically mixing method and in situ chemical synthesis [5,13]. Graphene oxide (GO), involving the functional groups such as hydroxyl and epoxy groups, could act as an oxidant for the stannous ions, which has been confirmed as an effective strategy for the fabrication of SnO 2 -graphene nanocomposites [14][15][16]. As the approach is based on the oxidation-reduction reaction between GO and stannous ions, the oxidation-reduction degree determines the final oxidation state of tin ions, compound degree between graphene and SnO 2 and corresponding lithium storage ability, which could be tuned by the GO loading.…”

Thermal Decomposition CharacteristicS of Ammonium Nitrate(v) in the Presence of Mn2O3/Graphene Oxides

“…This can be attributed to the decomposition of the labile functional groups, according to the DSC curve [17]. Many other researchers have also found the same results [54][55][56]. In other words, when the temperature exceeds 200 °C, the functional groups of GO can be destroyed.…”
