A scalable and facile synthesis of carbon nanospheres as a metal free electrocatalyst for oxidation of l-ascorbic acid: Alternate fuel for direct oxidation fuel cells

Electrochemical oxidation of l-ascorbic acid (l-AA) on carbon nanospheres (CNSs; ~ 250 nm) in neural media was investigated to use l-AA as an alternate fuel for direct oxidation fuel cells. Higher current density with lower onset potential was obtained for the oxidation of l-AA by modifying glassy carbon electrodes with CNSs based metal free electrocatalysts. Interestingly, these CNSs exhibits superior electrocatalytic performance and it could be due to due to their advantageous structural features.151
