Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania elektrokatalizatora zawierającego platynę na materiale węglowym, gdzie jako źródło platyny stosuje się kwas chloroplatynowy, który charakteryzuje się tym, że włókna celulozowe poddaje się procesowi karbonizacji i aktywacji, po czym otrzymany materiał węglowy przemywa się wodnym roztworem kwasu solnego, a następnie wodą, po czym osadza się na nim cząstki platyny poprzez proces sonikacji, suszenia i redukcji w atmosferze wodoru, po czym 10 mg materiału węglowego poddaje się dyspergowaniu w 0,02% wagowym roztworze nafionu, a następnie otrzymany materiał węglowy nakrapla się na folię grafitową, otrzymując elektrokatalizator, przy czym sonikacji poddaje się mieszaninę materiału węglowego z kwasem chloroplatynowym w rozpuszczalniku, tak aby stosunek wagowy materiału węglowego do platyny wynosił od 10:1 do 100:1.
