Abstract

Cobalt phosphite (Co(11)(HPO(3))(8)(OH)(6)) microarchitectures assembled by ultralong nanoribbons are successfully synthesized by a mild hydrothermal condition without any additives. The uniform ultralong nanoribbon has a width of 100 nm and length of 20-30 μm. More importantly, Co(11)(HPO(3))(8)(OH)(6) microarchitectures are also successfully applied as an electrochemical supercapacitor with a good specific capacitance (312 F g(-1) at 1.25 A g(-1)), good rate capability and excellent cycling property (maintaining about 89.4% at 1.25 A g(-1) after 3000 cycles).
