Cobalt-Incorporated Tellurium Nanostructured Electrocatalysts for Hydrogen Evolution Reaction in Acidic Electrolyte |
| 초록 |
In recent years, cobalt has often been incorporated into chalcogenides to form bifunctional electrocatalysts due to its abundance and environmentally friendly nature. Nanostructured tellurium is an emerging electrocatalyst support that can accelerate electron transportation. This study focuses on exploring the effects of using different amounts of cobalt incorporated tellurium nanostructured composites (CoTe2/Te) as electrocatalysts in HER with 0.5 M H2SO4 electrolyte. The electrocatalysts were prepared via a facile hydrothermal route. The highest HER activity was found while using the CoTe2/Te (Co:Te = 4:20) composite achieving overpotentials of 312 and 421 mV at 10 and 100 mA cm-2, respectively, with a tafel slope of 69.2 mV dec-1. The HER performance of the CoTe2/Te (Co:Te = 4:20) electrode was found to be superior to those of Te (commercial powder), Te (fabricated), and CoTe2 electrocatalysts. |
