COMPARATIVE STUDY OF Pt-BASED CATALYSTS SUPPORTED ON VARIOUS CARBON SUPPORTS FOR SOLID POLYMER ELECTROLYTE ELECTROCHEMICAL SYSTEMS

Abstract

The comparative study of electrocatalysts synthesized by chemical reduction and pulsed magnetron-ion sputtering for polymer electrolyte membrane electrochemical systems are presented. Various carbon nanomaterials were used as supports of Pt nanoparticles: carbon black, nanotubes, nanofibers and reduced graphene oxide. The electrochemical studies of the obtained electrocatalysts as well as their testing in the fuel cell membrane-electrode assembly were carried out. The influence of supports morphology and the deposition approach of Pt nanoparticles on the electrochemically active surface area and activity of electrocatalysts, as well as the prospects of the magnetron-ion sputtering approach for electrocatalysts synthesis were studied and discussed.

The Study of the Solid Polymer Electrolyte Oxygen Concentrator with Nanostructural Catalysts Based on Hydrophobized Support

“…The synthesis of cathode catalysts on different supports was performed by reducing the precursor of Pt nanoparticles H 2 PtCl 6 ⋅ 6H 2 O in an ethyleneglycol medium (“polyol” method) as detailed in [ 22 , 23 ].…”

Graphene and Graphene-Like Materials for Hydrogen Energy

“…Graphene also attracts great attention as a support of electrocatalysts for hydrogen-oxygen (-air) FCs [116][117][118][119].…”
