What is the Role of Catalysts in Renewable Electrolysis?
Catalysts play a crucial role in renewable electrolysis by lowering the activation energy required for the water-splitting reactions. In the process, two half-reactions occur: the oxygen evolution reaction (OER) at the anode and the hydrogen evolution reaction (HER) at the cathode. Effective catalysts enhance the rate of these reactions, thus improving the overall efficiency of electrolysis.
