Plasma-assisted Pt and Pt-Pd nano-particles deposition on carbon carriers for application in PEM electrochemical cells

► Plasma-assisted deposition of Pt and Pt-Pd nano-particles on carbon carriers. ► Vulcan XC-72, carbon nano-tubes and nano-fibers were used as catalysts carriers. ► The carbon nano-tubes and nano-fibers must be carefully pretreated. ► Catalysts exhibit high surface area, chemical purity and electrochemical activity.
