  5. 9. Analys av platinaytor och platinatennytor under katalytisk etanoloxidation med röntgenfotoelektronspectroskopi

    Magister-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Mats Viktor Löfstrand; [2023]
    Nyckelord :Pt3Sn; APXPS; Ethanol oxidation; Pt 111 ; Pt 223 ;

    Sammanfattning : Fuel cells are more efficient and cleaner than combustion engines. Ethanol as a fuel has a high energy density and is safer and easier to handle than hydrogen which is normally used in fuel cells. If efficient fuel cells on alcohol were available, they could be used for engines and power sources for electronics. LÄS MER
