Fabrication of CoTe2/Te composites for highly hydrogen evolution reaction in alkaline solution

With the increasing dependence of production and life on energy, low-cost and clean renewable energy has gradually become an attractive area for researchers. Considering that CoTe2 has metal conductivity, it can carry out more efficient electronic transport, that will significantly improve the catalytic performance. We prepared CoTe2/Te composite with regular morphology by one-step hydrothermal method. It showed good catalytic performance in 1 M KOH alkaline solution with the overpotential of 168 mV. We believe that the prepared CoTe2/Te composite can play an important role in the production of hydrogen in an alkaline environment.
