Abstract:Electrochemical energy storage and conversion using hydrogen has become important in the area of sustainable energy and development1. HER is one of the key reactions in alkaline water electrolysis and chlor-alkali industry2. Though water electrolysis is not a cost-effective method yet,it finds attention as it produces high purity hydrogen3.Platinum is a very active catalyst for HER.The mechanism of HER is believed to be a combination of three elementary steps, 1. the Volmer (V) step, where water molecules are … Show more
