AB  - Mixed transition metal sulfides with hollow structures hold great promise for 
      energy-related applications. However, most of them are in the powder form, which 
      should be mixed with unwanted polymer binders and conductive agents. In this 
      study, a facile two-step strategy has been developed to grow mesoporous and 
      hollow Ni-Zn-Co-S nanosword arrays (NSAs) on a nickel foam (NF) substrate with 
      robust adhesion, which involves the hydrothermal growth of bimetallic Zn-Co-ZIF 
      NSAs on NF and subsequent transformation into hollow Ni-Zn-Co-S NSAs through the 
      sulfurization process. Benefiting from the unique structural and compositional 
      advantages as well as directly grown conductive substrate, the Ni-Zn-Co-S-0.33 
      NSAs/NF electrode exhibits the best electrochemical performance when investigated 
      as a binder-free electrode for supercapacitors. Impressively, the Ni-Zn-Co-S-0.33 
      NSAs/NF electrode delivers a high areal capacity of 1.11 mA h cm(-2) at the 
      current density of 10 mA cm(-2), and the corresponding specific capacity is as 
      high as 358.1 mA h g(-1). Moreover, an asymmetric supercapacitor (ASC) device 
      based on the Ni-Zn-Co-S-0.33 NSAs/NF as the positive electrode and Bi(2)O(3)/NF 
      as the negative electrode has been successfully fabricated, and can deliver a 
      high energy density of 91.7 W h kg(-1) at a power density of 458 W kg(-1) and 
      maintain the energy density of 66.9 W h kg(-1) at a high power density of 6696 W 
      kg(-1). The electrochemical results suggest that the hollow Ni-Zn-Co-S NSAs would 
      possess great potential for applications in high-performance supercapacitors.
