Encapsulating platinum nanoparticles with nitrogen-doped graphene layers improves the catalytic activity of the particles, while making them more resistant to degradation. This is the new finding from researchers at the Korean Institute of Energy Research (KIER) and the University of Oxford in the UK, who say that their work could help make better proton exchange membrane fuel cells (PEMFCs) in the future……..
