“…[1][2][3][4][5][6][7] In addition, the electrochemical activation of carbon surfaces has been used for applications including electroanalytical chemistry and electrocatalysis. [8][9][10] Recently, it has been revealed that nitrogen atoms containing functional groups can be easily introduced onto the surfaces of glassy carbon (GC) electrodes by the electrode oxidation of ammonium carbamate in an aqueous medium at a highly positive electrode potential. We named this electro-oxidized GC electrode an aminated GC electrode.…”
