Cold Plasma Enhanced Active Sites On Supported Nip Nanoparticles For The Oxygen Evolution Reaction, Michael Ricci

Williams Honors College, Honors Research Projects

Identifying materials to efficiently facilitate the oxygen evolution reaction (OER) is key to advancing water electrolysis, an essential technology in the pathway towards a sustainable energy future. Here, we explore cold-plasma treatment as a facile method to enhance the activity of NiP nanoparticles supported on activated carbon. NiP nanoparticles were synthesized on an activated carbon support using a solid-state method and were then treated with argon, oxygen, and hydrogen plasmas for extended times. In all cases, plasma treatment reduced the number of active sites on the support. OER activity was evaluated by testing the materials in alkaline conditions. The activities …
