A general method for the synthesis of graphene oxide-metal sulfide composites with improved photocatalytic activities

Graphene‐integrated CuCo 2 S 4 microspheres as a sustainable anode material for high‐performance Li‐ion batteries

“…The representative XRD patterns of GO, CuCo 2 S 4 , and CuCo 2 S 4 ‐rGOare revealed in Figure 3A. As expected, GO exhibited a sharp and strong diffraction peak centered at 11.6°, which is corresponded to the reflection of the (001) plane 28 . A broad peak around 21° corresponded to the (002) plane, which may be associated with a small domain of coherent and parallel stacking of graphene sheets 29,30 .…”

A facile and simple approach to synthesis and characterization of methacrylated graphene oxide nanostructured polyaniline nanocomposites

“…Graphene and its derivatives are single layer sheets consisting carbon atoms [23], with SP 2 chemical bonds [4] forming a 2-D honeycomb crystal with precise atomic level organization [24,25]. Exceptional characteristics of graphene make an advanced material for several interesting applications such as facile processability, fast production in comparison with other nanoscale carbons [26] and brilliant properties including exceptionally wide porosity, zero band gap [27], superior mobility of charge carriers (200,000 cm 2 v −1 s −1 ) [28], very high specific surface area (2630 m 2 g −1 ), great flexibility [29], unique chemical stability [30], fast electron transfer, prominent conductivity and cost efficiency [31,32]. Due to superior features of graphene and its derivatives [33], some of them have remarkable attention comprising its exploitation as a functional substrate for prevention of nanoscale materials from aggregation and agglomeration [34] in catalysts [35], as a superb conductor in electrical devices and nanobiosensors, bio-acceptors in electrochemical sensing applications [36] and carriers [37] in drug delivery [38,39].…”

Synthesis of cadmium sulfide-reduced graphene oxide nanocomposites by pulsed laser ablation in liquid for the enhanced photocatalytic reactions in the visible light

“…8 The nanocomposites of CdS with 2 or more other functional materials have been tried to reduce the charge recombination by the formation of heterojunctions and thereby improving the composite efficiency of the material. 9 In this line, graphene was also used as a composite partner of CdS by many research groups [10][11][12] The structure of graphene is a flat monolayer network of sp 2 hybridized carbon atoms, tightly arranged in a 2dimentional (2D) honey comb structure, 13 and it is well known for its chemical stability, high specific surface area (approximately 2600 m 2 g −1 ), excellent electron mobility, and high thermal conductivity (approximately 5000 Wm −1 K −1 ). [13][14][15] Various methods of synthesis for cadmium sulfide/ reduced graphene oxide (CdS/rGO) nanocomposite were adopted and applied for many photo-catalytic applications.…”
