Investigation of catalytic vacuum black in the electrodes low-temperature electrochemical devices

Research of catalytic compositions based on noble metal black received by magnetron deposition of metal in vacuum thickness-control disclosed. Such blacks have unique bush-like structure formed by thin filaments of platinum with diameter near 10 nm and 200-300 nm long. This structure compared with structure of platinized platinum received by electrochemical deposition from solution. On basis of electrochemical research disclosed that vacuum platinum blacks (VPB) based on titan nickel and carbon provide high activity in anode hydrogen oxidation reaction and cathode hydrogen restoration in low temperature electrochemical devices.
