STRATEGY aims at demonstrating a radically new approach to design catalyst layers (CL) for energy devices as fuel cells, based on Laser-Induced Graphene with Hierarchical pore structure (H-LIG) and controlled composition obtained under ambient conditions from electrospun-1D nanofibers (NFs) of synthetic polymers after alkaline treatment. During laser processing, the conversion of NFs into graphene will induce the crystallization of metal-oxide (MO) nano-catalysts (NCs). This project will prove the possibility to control NCs nucleation at the surface of H-LIG NFs by laser writing and will show that NFs made of N-rich polymers mixed with MO precursors enable the creation of H-LIG with enhanced durability, stability and catalytic activity toward the oxygen reduction reaction (ORR).
