Correction to: Nature Communications 10.1038/s41467-018-03553-w, published online 23 March 2018.
The original version of this Article contained an error in Fig. 3c, g, in which the data series in red was incorrectly labelled as ‘NH2- oxid. rate’, rather than the correct ‘NO2- oxid. rate’. This has been corrected in both the PDF and HTML versions of the Article.
