Simulations of CNT/GP micro-conduit electrodes in 1 M H2SO4 at a voltage of 1 V. a Contour plot of counter-ion (SO42–) distribution (initial density: 1 M). b Contour plot of co-ion (H+) distribution (initial density: 2 M). c Contour plot of surface charge density distribution . d Comparisonof surface charge density between CNT/GP and bare CNT cases. The magenta line corresponds to the path x1–x2 passing through both edge and basal regions of a typical petal in the CNT/GP case, and blue line corresponds to the path x3–x4 on the top outer surface of a bare CNT along its axial direction
