Abstract
The development of extremely efficient, low-cost, and stable electrocatalysts is required for the sluggish oxygen evolution reaction. Strontium telluride multi-skinned nano balls deposited on glassy carbon (SrTe/GC) were fabricated using the hydrothermal technique and were characterized via different analytical instruments. The fabricated SrTe/GC nanoballs underwent electrochemical measurement, achieving a low overpotential of 268 mV at 10 mA/cm(2) with a smaller Tafel slope of 25 mV/dec. The fabricated material also exhibited excellent stability for 24 h with no decline in current density. Hence, this study shows that strontium telluride could function as an extraordinarily efficient and stable electrocatalyst in future energy conversion applications.
