The oxygen reduction reaction (ORR) activity and stability of Pt catalysts deposited on graphene-coated alumina nanofibres (GCNFs) were investigated. The GCNFs were fabricated by catalyst-free chemical vapour deposition. Pt nanoparticles (NPs) were deposited on the nanofibres by sonoelectrochemical and plasma-assisted synthesis methods.

- Highly active electrocatalysts for the oxygen reduction reaction (ORR) were created using a pyrolysis process involving 5-methylresorcinol, cobalt, iron salts, and dicyandiamide.
- The bimetallic catalyst featuring iron and cobalt (FeCoNC-at) exhibited strong stability and ORR performance similar to commercial platinum-based catalysts.
- Performance tests in an anion exchange membrane fuel cell (AEMFC) demonstrated a peak power density of 415 mW cm, showcasing the catalyst's effectiveness.
In this work He/H plasma jet treatment was used to reduce Pd ions in the aqueous solution with simultaneous deposition of created Pd nanoparticles to support materials. Graphene oxide (GO) and nitrogen-doped graphene oxide (NrGO) were both co-reduced with the Pd ions to formulate catalyst materials. Pd catalyst was also deposited on the surface of carbon black.
