“…Thanks to its high theoretical capacitance and rapid faraday redox reaction, RuO 2 is thought to be an optimal pseudocapacitive electrode material [ 44 , 45 , 46 ]. However, its high price and toxicity to the environment seriously hinder its application in supercapacitors [ 47 , 48 , 49 ]. Co 3 O 4 , MnO 2 , and ZnO have the advantages of being natural abundant and high specific capacitance, which makes them substitutes for RuO 2 [ 50 , 51 ].…”

In the past decades, the energy consumption of nonrenewable fossil fuels has been increasing, which severely threatens human life. Thus, it is very urgent to develop renewable and reliable energy storage devices with features of environmental harmlessness and low cost. High power density, excellent cycle stability, and a fast charge/discharge process make supercapacitors a promising energy device. However, the energy density of supercapacitors is still less than that of ordinary batteries. As is known to all, the electrochemical performance of supercapacitors is largely dependent on electrode materials. In this review, we firstly introduced six typical transition metal oxides (TMOs) for supercapacitor electrodes, including RuO2, Co3O4, MnO2, ZnO, XCo2O4 (X = Mn, Cu, Ni), and AMoO4 (A = Co, Mn, Ni, Zn). Secondly, the problems of these TMOs in practical application are presented and the corresponding feasible solutions are clarified. Then, we summarize the latest developments of the six TMOs for supercapacitor electrodes. Finally, we discuss the developing trend of supercapacitors and give some recommendations for the future of supercapacitors.

Three dimensional (3D) Mo-doped nickel sulfide (Ni 3 S 2 ) mesoporous nanostructures on Ni foam were successfully synthesized via the solvothermal method, which showed the superior properties for energy storage and conversion. As an electrode for supercapacitor, 3D Mo-doped Ni 3 S 2 mesoporous nanostructures demonstrated a 604.4 μAh cm -2 specific capacity and good cycling stability. Furthermore, Mo-doped Ni 3 S 2 mesoporous nanostructures exhibited superior hydrogen evolution reaction and oxygen evolution reaction properties and good cycle stability for water splitting. At 1.41 V, the electrolyzer made up of Mo-doped Ni 3 S 2 mesoporous nanostructures reached the 10mA cm -2 catalytic current density, demonstrating outstanding long-term durability. Furthermore, the physical characterization results and mechanism of the 3D Mo-doped Ni 3 S 2 were investigated. Therefore, the study presents the great promise of the 3D Mo-doped Ni 3 S 2 mesoporous nanostructures in energy conversion and storage.

Engineering the electronic structure of HER catalysts has been suggested to improve the performance of noble metal‐free catalysts in alkaline electrolytes. Herein, we demonstrated that a suitable cation doping in the tungsten oxide catalyst modified the interfacial structure, surface chemical state and band gap value, which enhanced the HER performance. For the experiments, the cation (Ni, Co and Fe) doped tungsten oxide catalysts were synthesized on nickel foam, on which Ni‐based alloy was decorated. The Co doped catalyst (Co−WO) exhibited an extraordinary HER activity, with a low overpotential of 30 mV at a current density of 10 mA cm−2, Tafel slope of 32 mV dec−1. In this system, the Ni‐based alloy–tungsten oxide interface facilitated water dissociation. Moreover, the decreased band gap and improved conductivity induced by Co doping, further enhanced the charge transfer ability in the HER process. The regulated metal‐oxide heterostructure coupled with cation doping endowed the catalyst with efficient interface active sites, superior electrical conductivity, and enhanced electron transfer kinetics, facilitating the HER performance.
