Corrigendum: Graphene Oxide Nanoribbons from the Oxidative Opening of Carbon Nanotubes Retain Electrochemically Active Metallic Impurities

The authors wish to rectify the reported concentrations of metals in MWCNTs and GONRs used in the study. The concentrations of metals obtained from ICP-MS data reported in the original Communication were presented as obtained directly from the equipment without taking into account the dilution factor introduced during the microwave digestion procedure. This error in no way affects the conclusions of the paper. The following changes should be applied to the article text to reflect the true concentrations of the metals in the carbon materials:

page 8685, column 1:

“parts-per-billion” change to “parts-per-million”

page 8686, column 2:

“1130.9 ppb to 28.6 ppb” change to “5463.3 ppm to 193.2 ppm”

“20.7 ppb to 1.9 ppb” change to “100.2 ppm to 13.0 ppm”

“78.6 ppb to 46.5 ppb” change to “379.5 ppm to 314.0 ppm”

page 8687, column 1:

“ppb” change to “ppm”

“less than 2 ppb” change to “13 ppm”

page 8687, column 2:

“ppb” change to “ppm”
