“…The capacitance of the NiS 2 /MoS 2 /rGO nanocomposite, rGO, NiS 2 , and MoS 2 was evaluated by GCD measurements at different current densities, which are presented in Figure c and Figures S4b and S5c, d. The symmetric profiles of NiS 2 , MoS 2 , and NiS 2 /MoS 2 /rGO reveal a good reversibility of faradaic redox reactions that agrees well with CV results . When compared with that of NiS 2 and MoS 2 in Figure d, the NiS 2 /MoS 2 /rGO nanocomposite shows the longest discharge time.…”

Electrode material plays a critical role in both electrochemical energy storage and sensors, and there is an urgent need to develop novel electrode materials with high reactivity and catalytic activity. Herein, a multicomponent NiS2/MoS2/rGO electrode nanomaterial consisting of self-stacking NiS2 microblocks, hydrangea-like MoS2 nanosheets, and ultrathin reduced graphene oxide (rGO) nanolayers is synthesized via a facile two-step hydrothermal process. The ingenious combination of NiS2, MoS2, and rGO provides the nanocomposite good capacitance and sensitivity in electrochemical applications. As a result, the NiS2/MoS2/rGO nanocomposite exhibits a good specific capacitance of 645.3 F g–1 at 0.5 A g–1 and rate performance of 126.7 F g–1 at 10 A g–1. The assembled asymmetric supercapacitor of NiS2/MoS2/rGO//activated carbon delivers a high energy density of 19.4 Wh kg–1 at a power density of 156.1 W kg–1 for electrochemical energy storage. In addition, the electrochemical sensor based on a NiS2/MoS2/rGO nanocomposite modified onto glassy carbon electrode (GCE) shows superior activity toward detection of bisphenol A (BPA) compared with other reported electrochemical sensors. A wide linear range of 0.02–200 μM and a low detection limit of 2.1 nM can be obtained under the optimal conditions. This work provides insights into the development of multicomponent NiS2/MoS2/rGO electrode nanomaterial, including its facile synthesis method, good specific capacitance, and ultrasensitive detection of BPA, that exhibits bifunctional electrochemical applications.

“…4a displays the cyclic voltammetry (CV) curves of the NiCo 2 Se 4 HMSs electrode at different scan rates ranging from 5 to 60 mV s −1 in the potential windows of −0.2-0.8 V, which exhibit a pair of obvious redox peaks, indicating reversible and rich redox reactions of Co 2+ /Co 3+ and Ni 2+ /Ni 3+ . [78][79][80] It is worth noting that the shapes of CV curves are maintained as the scan rates increase from 5 to 60 mV s −1 , implying that the NiCo 2 Se 4 HMS electrode has a superior rate capability and remarkable electrochemical kinetics. The charge-discharge (GCD) curves at different current densities from 1 to 20 A g −1 in the potential range of 0.0 and 0.5 V are shown in Fig.…”

A soft template and hydrothermal method are used to prepare NiCo2S4 nanocone arrays/P‐doped hollow carbon nanospheres (NCS NCAs/PHCS). PHCS is loaded with a large number of vertically grown NCS NCAs on the surface due to phosphorus doping. PHCS is an excellent conductive base material and it can effectively alleviate the structural collapse of NCS NCAs during charging and discharging because of its hollow structure. NCS NCAs with lots of active sites provide fast diffusion channels and excellent electron transmission channels. The synergistic effect between NCS NCAs and PHCS causes the electrode material to show excellent electrochemical properties, such as high specific capacitance (761 C ⋅ g−1 at 1 A ⋅ g−1) and excellent cycle stability (the capacitance retention rate is 88.6 % after 10, 000 cycles at 20 A ⋅ g−1). The NCS NCAs/PHCS composite is also assembled with PHCS as an asymmetric supercapacitor. It shows a remarkable energy density of 46.5 Wh ⋅ kg−1 at the power density of 777.5 W ⋅ kg−1. These findings confirm that the NCS NCAs/PHCS composite is an excellent electrode material of supercapacitors.
