The original version of this article was inadvertently misplaced Fig. 1a and Fig. 1c with each other. The correct results (Fig. 1) are showed as follows.

a, b SEM images of the pure MnO2 nanorods; c, d SEM images of the MnO2@C composite nanorods

Moreover, the letters marked in all the figures of the whole article should be lower case rather than capital letter.
