With an increasing demand for clean and sustainable energy which is directly related to water splitting, regenerative fuel cells, metal-air batteries, etc., exploring an efficient and inexpensive electrocatalyst with highly stable for oxygen evolution reaction (OER) is very important. In this article, here we demonstrated the nanorod Zn-Co-Te, is found to be a very good electrocatalyst for oxygen evolution reaction (OER) in alkali medium (KOH, pH = 15.14) with onset potential 1.38 V vs RHE. When this catalyst used as an electrocatalyst Zn-Co-Te nanorod obtained low overpotential 221 mV at a 10 mAcm −2 current density with Tafel slope 91 mV/dec and high stability within three months.
