Iron/Iron(III) Oxide Decorated on Electrochemically Reduced Graphene Oxide: a Novel One-Step Electrosynthesis and a Fabrication of an Electrochemical Ascorbic Acid Sensor
Considering on required detection time and sensitivity, electrochemical method is an excellent candidate for ascorbic acid (AA) sensing. We propose using the synergistic effects of iron(0)/iron(III) oxide decorated on the electrochemically reduced graphene oxide (ERGO/Fe-Fe 2 O 3 ) modified Pt micro...
