“…The presence of ZnO-NP in the Nafion matrix accelerates the electron transfer by reducing the R ct at 45.33 kΩ. This easier electron transfer process, proved by the lowest value of charge transfer resistance, could be attributed to a large number of active sites of ZnO-NP which enhanced the conductivity and the electron transfer process at the nanostructured surface of the modified electrode [37,39,40].…”

ZnO nanoparticles (ZnO‐NP) were prepared by a facile precipitation technique using di‐isopropyl amine as precipitating agent. The morpho‐structure and porosity of the as‐prepared nano‐powder were investigated by FT‐IR analysis, X‐ray diffraction (XRD), scanning electron microscopy (SEM), and BET analysis. By drop‐casting, a composite film was deposited to obtain ZnO‐NP‐Nafion/GCE modified electrode. The modified electrode was investigated by cyclic voltammetry, electrochemical impedance spectroscopy, and square wave anodic stripping voltammetry (SWASV) for the detection of Pb2+, Cd2+, Cu2+, and Fe3+, and it was successfully applied for the detection of Pb2+ and Cu2+ in real water samples.

MXene (2D titanium carbide) as the electrode material for supercapacitors has been studied extensively and deeply in recent years. In order to enhance the electrochemical performance of MXene, CoS2 nanoparticles grown on MXene surface are constructed by a simple one‐step solvent thermal method. CoS2 nanoparticles play a crucial part in increasing the active sites of metal ions on the surface of MXene. In three‐electrode system, the obtained MXene/CoS2 composite delivers high performance. Its specific capacitance can be up to 1320 F g−1 at a current density of 1 A g−1 and it shows remarkable cycle performance with 78.4% after 3000 cycles at 10 A g−1. Moreover, the asymmetric supercapacitors (ASCs) with reduced graphene oxide as the negative electrode and MXene/CoS2 composite as the positive electrode exhibit a wide potential window of 1.6 V and high energy density (28.8 Wh kg−1) at a power density of 800 W kg−1. After 5000 cycles, the ASCs maintain 98% of initial specific capacitance at 5 A g−1. These results can effectively promote the application in the supercapacitor materials.
