Mild, but strong enough: A green electrochemical method is presented to prepare graphene oxide nanosheet-modified electrodes insitu. The modified electrodes show a very good electrochemical catalytic activity to ascorbic acid. The as-prepared nanosheets, naturally fixed on the electrode, have a low degree of oxidation and can be easily reduced electrochemically insitu.
