Abstract
To meet the energy demand of modern civilization, efforts to find renewable, safe, and highly effective fuel generation are still a big challenge. The oxygen evolution reaction (OER) is one of many modern technologies for hydrogen generation, and a number of new electrode materials have been created to increase the effectiveness of O(2) evolution. This project utilizes a range of high performance nanomaterials, such as Pr-MOF, Fe(2)O(3), and Pr-MOF/Fe(2)O(3), to carry out the oxygen evolution reaction. This study shows that Pr-MOF/Fe(2)O(3) exhibits exceptional electrocatalytic activity in alkaline solution with 238 mV overpotential at the current density of 10 mA cm(-2) and a Tafel slope of 37 mV dec(-1) which is much lower when compared to pure Pr-MOF and Fe(2)O(3). The enhanced electrochemical results are due to the higher electrochemical surface area of 237 cm(2). This work will lay the foundation for an approach to enhance the crystalline nature of surface-active nanoparticles made from rare earth MOFs for a range of electrochemical energy applications.
