Nickel oxide carbon nanofiber composite for electrochemical oxidation of methanol
Al-Enizi, Abdullah M.; El-Zatahry, Ahmed A.; Abdullah, Aboubakr Moustafa; Al-Deyab, Salem S. ( Electrochemical Society Inc. , 2014 , Conference Paper)Electrospun fibers of a mixture of polyvinylpyrrolidone (PVP), polyaniline (PANI) and graphene were stabilized for 2 h at 200 °C and then carbonized at 800 °C for 5 h. Composites were prepared by depositing Ni(OH)2 on the ...
