The CoTe2 nanostructure: an efficient and robust catalyst for hydrogen evolution

Abstract

Cobalt ditelluride nanoparticles in a diameter range of 20–50 nm were synthesized as a new electrocatalyst for the hydrogen evolution reaction in 0.50 M H2SO4(aq). These nanoparticles can generate −10 mA cm−2 at an overpotential of 246 mV without any decay up to 48 h of continuous reaction.
