文摘

Ultralong cobalt sulfide (CoS_1.097) nanotube networks are synthesized by a simple one-step solvothermal method without any surfactant or template. A possible formation mechanism for the growth processes is proposed. Owing to the hollow structure and large specific area, the novel CoS_1.097 materials present outstanding electrochemical properties. Electrochemical measurements for supercapacitors show that the as-prepared ultralong CoS_1.097 nanotube networks exhibit high specific capacity, good capacity retention, and excellent Coulombic efficiency.
