N-doped carbon dots regulate porous hollow nickel-cobalt sulfide: High-performance electrode materials in supercapacitor and enzymeless glucose sensor

Transition metal sulfides (TMSs) are expected to be a new type of electrode material due to their excellent electrochemical activity. However, the poor capacity retention and stability of TMSs are obstacles to their practical application. Here, the porous hollow nickel-cobalt sulfides are fabricated via a simple water bath followed by anion exchange, which can be regulated by N-doped carbon dots (NCDs). Newly designed porous hollow structure...
