Abstract

Cobalt telluride branched nanostructures on carbon fiber paper (CFP) with two different morphologies were synthesized via solution-based conversion reaction. Both the CoTe₂ with nanodendrite and CoTe with nanosheet morphologies on the CoTe₂ nanotube (CoTe₂ NDs/CoTe₂ NTs and CoTe NSs/CoTe₂ NTs) supported by CFP exhibit high activities toward hydrogen evolution reaction (HER). Particularly, the CoTe NSs/CoTe₂ NTs only require an overpotential of 230.0 mV to deliver the current density of 100 mA cm^-2 in acid solution. After cycling for 5000 cycles or 20 h continual electrolysis, only a small performance loss is observed.
