Hierarchical CoTe2 Nanowire Array: An Effective Oxygen Evolution Catalyst in Alkaline Media

ACS Sustainable Chemistry and Engineering, Volume 6, No. 4, Year 2018

In this Letter, we report the development of hierarchical CoTe2 nanowire array on Ti mesh (CoTe2 NA/TM) via topotactical conversion from its Co(OH)F precursor through hydrothermal tellurization reaction. As a 3D oxygen evolution electrocatalyst, such CoTe2 NA/TM exhibits excellent catalytic activity with an overpotential of 340 mV to attain 50 mA cm-2 in 1.0 M KOH. Notably, it also exhibits high durability for 25 h.
