In this paper we reproduced some Figures and a Table (Fig. 1 A,B; Fig. 2 B,C,D; Fig. 3 A,B,C; Fig. 4; Fig. 5; Table S1) that had been previously published in another paper of ours (Electrochim. Acta, 2013, 114, 726–735). The material reported in the two papers is the same but shows a different focus. Accordingly, we neglected to indicate a difference between them. We are very sorry for this mistake, but have now obtained a formal permission statement from Electrochimica Acta for the republication of these Figures and the Table.

The Royal Society of Chemistry apologises for this error and any consequent inconvenience to authors and readers.
