Moving from flat to curved catalytic carbon supports could help reduce the amount and cost of platinum needed for hydrogen production in water splitting. In a new study published in Nature Energy, aimed at improving the efficiency of electrocatalytic processes, a team of scientists led by Li Song and Jun Jiang from the University of Science and Technology of China (USTC) used platinum decorated spherical onion-like carbon (OLC) catalysts with platinum atoms deposited on their outermost surface instead of flat graphene supports. This method reduced the amount of platinum atoms otherwise needed by about 75% while maintaining or improving the rate of the electrochemical hydrogen production process.
