CeNS Bengaluru develops high-entropy alloy catalyst for efficient green hydrogen
On 3 February 2025, in Bengaluru, Karnataka, the Department of Science and Technology announced that the Centre for Nano and Soft Matter Sciences had developed a high-entropy alloy catalyst, PtPdCoNiMn, for efficient hydrogen production by water electrolysis.
Summary
On 3 February 2025, in Bengaluru, Karnataka, the Department of Science and Technology (DST) announced that researchers at the Centre for Nano and Soft Matter Sciences (CeNS), an autonomous DST institute, had developed a novel high-entropy alloy (HEA) catalyst, PtPdCoNiMn, made of platinum, palladium, cobalt, nickel and manganese, for producing hydrogen by electrolysis of water. The catalyst uses seven times less platinum than a commercial catalyst and offers better catalytic efficiency than pure platinum, with high durability and long-term stability. High-entropy alloys contain multiple elements, usually five or more, in almost equal concentrations.
