a I−V curves of SP/AAO nanochannels after different UV irradiation times. I−V curves of SP/AAO nanochannels treated with SO2 after UV activation for (b) 1 min, (c) 5 min, (d) 10 min, and (e) 20 min. f Corresponding SO2 response current (\({{{\rm{I}}}_{{{{\rm{SO}}}}_{2}}}\)). Error bars in f denote the standard deviation from three different samples. MC (UV 1 min): MC-state nanochannels obtained after 1 min of UV irradiation. MC (UV 5 min): MC-state nanochannels obtained after 5 min of UV irradiation. MC (UV 10 min): MC-state nanochannels obtained after 10 min of UV irradiation. MC (UV 20 min): MC-state nanochannels obtained after 20 min of UV irradiation.
