Correction to: Metal and Nonmetal Codoped 3D Nanoporous Graphene for Efficient Bifunctional Electrocatalysis and Rechargeable Zn–Air Batteries (Advanced Materials, (2019), 31, 19, (1900843), 10.1002/adma.201900843)

Adv. Mater. 2019, 31, 1900843 The authors realized there was a mistake in Figure 3i in the originally published article, which arose in preparation of the figure. After correction, the new Figure 3i is shown as below. 3 Figure (Figure presented.) i) Free energy diagram for OER process. With the correction, the description of the figure should also be modified. To be specific, the sentence on page 5 of 7 “For the OER, the rate-limiting steps for both the co-doped graphene and N single-doped graphene correspond to the formation of O* species (Figure 3i)” should now read “For the OER, the rate-limiting steps for three systems correspond to the formation of O* species (Figure 3i)”, and the sentence “Note that the rate-limiting step for Ni single-doped graphene changes to the formation of OH* species and the overpotential is higher than that of the co-doped graphene (Figure 3i)” should be deleted. The authors apologize for any inconvenience that may have been caused due to these errors.
