High-performance supercapacitor based on Cu2O/MoS2/rGO nanocomposite

Label-Free Electrochemical Biosensor Based on Au@MoS₂–PANI for Escherichia coli Detection

“…The powder XRD pattern shows that the MoS 2 sample is pure, crystalline, and has high phase purity (Figure S1). The detectable diffraction peaks (2θ) at 14.09 • , 33.24 • , 39.33 • , 49.58 • , and 58.99 • are well matched with (002), ( 101), ( 103), (105), and (110) planes of the standard XRD data for the hexagonal structure of MoS 2 [37,38]. The low-magnification TEM image of MoS 2 shows that several layers are aggregated together, as shown in Figure 1A.…”

Recent advances in hierarchical MoS2/graphene-based materials for supercapacitor applications

“…It is proposed that the hierarchical MoS 2 /G network needs further research for practical applications of supercapacitors. 72 MoS 2 /rGO and a-Fe 2 O 3 /MoS 2 / rGO composite were fabricated by two consecutive microwave reactions. It was observed that the Fe 2 O 3 spherical nanoparticles were wrapped by the MoS 2 /rGO nanosheets (Fig.…”

“…For example, Vijaya et al prepared the α-Fe 2 O 3 /MoS 2 /rGO composite through a cost-efficient microwave strategy. 72 MoS 2 /rGO and α-Fe 2 O 3 /MoS 2 /rGO composite were fabricated by two consecutive microwave reactions. It was observed that the Fe 2 O 3 spherical nanoparticles were wrapped by the MoS 2 /rGO nanosheets (Fig.…”

“…Similarly, the Cu 2 O/MoS 2 /rGO nanostructures were assembled by decorating the Cu 2 O nanospheres with layered MoS 2 /rGO nanosheets via a microwave method. 73 The large-scaled rGO nanosheets serve as the bridge, integrating Cu 2 O nanospheres and MoS 2 nanosheets (Fig. 9B and b 1 ), favoring the merits such as numerous active sites, high conductivity, and synergistic effect for high electrochemical performance.…”

Copper oxide nanostructured thin films processed by SILAR for optoelectronic applications

“…Cu x O semiconductors are very attractive and have been broadly studied in both theoretical analysis and investigations into applied executions of nano or optoelectronic devices due to their chemically stable nature, nontoxicity, relative abundance, potential particle size effects, excellent performance as a catalyst, and fulll all the requirements for low-cost manufacturing at ambient conditions, which have high potential usage in energy storage, conversion, and next-generation rechargeable lithium-ion batteries. [1][2][3][4][5][6] Furthermore, Cu x O nanostructures are extensively used in other diverse applications, including photovoltaics, 7 photodetectors, 8 nanouid, 9,10 energetic materials, 11 eld emissions, 12 supercapacitors, 13,14 biosensors, 15,16 gas sensors, 17,18 photocatalysis, 19,20 removal of inorganic pollutants, 21,22 and magnetic storage media. 23,24 Both the Cu 2 O and CuO show direct transition nature with a direct band gap of around 2.1 and 1.5 respectively, having a high extension coefficient of above 10 5 cm −1 .…”
