Correction to: Nature Energy https://doi.org/10.1038/s41560-019-0333-2, published online 11 March 2019.

In the version of this Article originally published, in Fig. 3b the wrong experimental data, the concentration of hydrogen (vol. %), were plotted for the black and blue curves, instead of the hydrogen production rate. In addition, in the legend, in the label for the blue curve ‘500 °C’ should have been ‘550 °C’. Furthermore, in Fig. 3b,f, the units on the y axis “ml–1 min–1 cm–2” were incorrect and should have been “ml min–1 cm–2”. The original and corrected Fig. 3b are shown below. These errors have been corrected in all versions of the Article.
