 The researchers developed a new type of material consisting of platinum and earth abundant transition metals, deposited onto graphene nanoplatelets. This material was then tested for its ability to catalyze both oxygen evolution reaction, OER, and oxygen reduction reaction, ORR. The results showed that the material had high catalytic activity for both reactions, making it suitable for use in regenerative fuel cells and metal-air batteries. Furthermore, the researchers found that a two-step synthesis process improved the material's performance, allowing more efficient access to the active sites and reducing the charge transfer resistance.
