Synthesis of rambutan-like MoS2/mesoporous carbon spheres nanocomposites with excellent performance for supercapacitors

Synthesis of N, P dual‐doped MoS 2 on hollow carbon spheres for hydrogen evolution reaction

“…The distribution of MoS 2 nanosheets on the surface of P-MoS 2 @NCs-2 are quite uniform without obvious aggregation, which is in agreement with the FE-SEM image (Figure 2C). As shown in Figure 2E, the interlamellar spacings of P-MoS 2 @NCs-2 were determined to be 0.64 and 0.27 nm, which is consistent with the (002) 23 and (100) planes, 9 respectively. The SAED pattern (Figure 2E) indicate that the MoS 2 has the poor crystallinity with hexagonal structure.…”

“…The SAED pattern (Figure 2E) indicate that the MoS 2 has the poor crystallinity with hexagonal structure. 23 In addition, EDS elemental mapping (Figure 2F) shows the C, N, P, S, and Mo are homogeneously dispersed throughout the whole spheres of P-MoS 2 @NCs-2. The ratio of total S and P atoms to Mo is about 2.09, indicating P atoms successfully replaced the S atoms and were doped into the materials (Figure S3).…”

“…19,20 Due to the layer structure, agglomeration of MoS 2 will severely occur during the hydrothermal process, which is quite unfavorable for the exposing of edged active sites. 21,22 To produce more active sites, lots of approaches have been proposed to fabricate 3D MoS 2 , 23,24 which can prevent the aggregation of MoS 2 .…”

Hierarchical MoS2 microspheres prepared through a zinc ion-assisted hydrothermal route as an electrochemical supercapacitor electrode

“…29,30 Hierarchical nanostructures, which are assembled from 0D, 1D and 2D nanomaterials as building blocks have attracted signicant attention based on the fact that the hierarchical structures could supply efficient channels for transport of both electrons and ions, exhibit high surface area, shorten ion diffusion length, strengthen the structural stability and thus improve their electrochemical performance. [31][32][33] Various MoS 2 hierarchical nanostructures such as binder-free nanoarrays, nanosponges and nanoowers have been reported to manifest superior electrochemical performances.…”

Annealing Boosts the Supercapacitive Properties of Molybdenum Disulfide Powder

“…Although MoS 2 powder has impressive properties for energy storage, it has poor carrier mobility [4,5]. Several approaches to improve the carrier mobility of MoS 2 powder for energy storage involve incorporating carbonbased materials like graphene, onion-like carbons polyaniline, polypyrrole and carbon nanospheres [6][7][8][9][10][11]. Another technique that has also shown improvement in bulk MoS 2 in terms of enhanced capacity is metal ion implantation [12][13][14][15].…”
