Figure 6

Cyclic voltammograms of POAP films (46 mC cm−2) on different carbon electrode substrates in 0.1 M H2SO4: (a) original GC electrode, (b) chemically pretreated electrode using 98% sulphuric acid for 10 min, (c) electrochemically pretreated GC electrode at 1.85 V for 5 min, then cycled between −0.2 V and 0.7 V for another 15 min in 0.1 M H2SO4 [15].
