TL;DR: In this paper, an eco-friendly, in-situ, and one-step synthesis of ZnO-Co3O4 core-shell heterostructure (ZC-CSH) using the hydrothermal process as a transcendent nanomaterial for the supercapacitor applications was reported.

TL;DR: The NiO/NiO supercapacitor showed a high specific capacitance at 6.7 A g−1, energy density (22.1 W−h−kg−1), and excellent power density (15,250 W−k−1) after 10,000 GCD cycles.

TL;DR: In this article , oxygen vacancy was introduced into Co 9 S 8 @MnO 2 core-shell heterostructure arrays via a simple ambient process, which can effectively improve the reaction kinetics of MnO 2 and increase the electrochemical active sites.

TL;DR: In this paper , the performance of different types of nano/micro hybrid structures derived from the metal-organic framework as electrode materials for supercapacitor applications is discussed, and the emerging feasibility of large-scale production, challenges and future perspectives are systematically discussed.

TL;DR: In this paper , a newly designed ZnO covered with ZnS and paired with CdS to produce a ternary heterostructure was presented, which improved the electrochemical properties of individual constituents, e.g., a capacity of 434 mAh g−1, and charged transfer kinetics.
