Enzymatic Biofuel Cell Using Graphene Electrodes with Improved Interfacial Electron Transfer

One-step synthesis of Ni(OH)2/MWCNT nanocomposites for constructing a nonenzymatic hydroquinone/O2fuel cell

“…As can be read, a peak power density of 0.24 mW cm À2 at an open circuit voltage (V oc ) of around 0.49 V was obtained (curve c and c1). Most strikingly, the value of P max of the Ni(OH) 2 /MWCNTs based biofuel cell is distinctly higher than the previously reported enzyme-based BFCs 31,32 or precious metal-based BFCs. 33,34 Furthermore, the electrocatalytic performance of Ni(OH) 2 /MWCNTs is better than single Ni(OH) 2 or MWCNTs catalysts, which indicates that the prepared composites is more suitable as an anode catalyst for biofuel cells.…”
