In the version of this article originally published, in Supplementary Fig. 16a, there were errors in the XRD data. The data were presented between 2θ values of 5–40° and the dataset for each sample was presented as one measurement but was actually made up of data from two sets of measurements using two 2θ ranges of 5–10° and 10–40° with different time collection periods of 0.5 s and 0.2 s for each single point, respectively. In assembling Supplementary Fig. 16a, the high-angle data (10–40°) for the “before catalysis” sample were mistakenly imported for both the “before catalysis” and “after catalysis” samples, after which smoothing operations were performed on the data. This resulted in the plots for the “before catalysis” and “after catalysis” samples mistakenly having the same raw data between 10–40°. Although the raw data were identical between 10–40°, there were small variations between the two plots shown for the “before catalysis” and “after catalysis” samples due to slight differences in the smoothing operations. The correct data for the “after catalysis” sample are now included, and data for both samples are presented in separate graphs in Supplementary Fig. 16a for the 5–10° range and for the 10–40° range, to reflect the fact that two separate measurements were performed. The corrected data presented are unprocessed. The data shown for the “before catalysis” sample was presented correctly as originally published but is now shown as unprocessed data for consistency with the “after catalysis” sample. The Supplementary Information has been updated in the original article; for comparison, the original and corrected Supplementary Fig. 16a are included in the Supplementary Information file that accompanies this notice.
