Abstract
Developing low-cost, highly active electrocatalysts for electrochemical water splitting is crucial for decreasing the demand for energy in the future. Water splitting has been addressed as a feasible option for storing electrical energy. Researchers are interested in designing non-toxic, high-performance, and cost-effective catalysts for the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER). Herein, spherical structured Ti(0.5)Sr(0.5)O(3) catalysts, which are materials made from titanium and strontium oxides, are produced using a simple solid-state technique. XRD, Raman, FE-SEM, TEM, XPS, and FT-IR spectroscopy were performed to confirm the crystal structure, morphology, and element composition of the Ti(0.5)Sr(0.5)O(3). In alkaline electrolyte 1.0 M KOH solution, Ti(0.5)Sr(0.5)O(3)/NF has good OER activity, with an overpotential and a Tafel slope of 299 mV and 152.5 mV dec(-1), respectively. It also exhibits strong HER activity, with overpotential and a Tafel slope of 101.6 mV and 179 mV dec(-1), respectively. The present research employs an innovative development approach for a low-cost, highly efficient water-splitting catalyst that aligns with the United Nations' Sustainable Development Goal 7 for affordable and clean energy.
