Pt- and Ir-based disperse catalysts synthesized in a magnetron for water electrolyzers with a solid polymer electrolyte

Disperse catalytic compositions for water electrolysis in electrolyzers with a solid polymer electrolyte were obtained by magnetron sputtering of C–Pt and Mo–Ir sectional targets. The catalysts were studied by X-ray diffraction analysis, electron microscopy, and voltammetry. The synthesized Pt–С and Ir–Mo catalysts with lowered contents of the precious component were subjected to prolonged trials in an electrolysis cell with a solid polymer electrolyte and showed high activity and stability.
