The cover picture shows the geologic features in the Valley of Fire State Park (Nevada, USA, photo courtesy Frank Kovalchek), which exhibit a red‐orange color due to the large concentration of iron oxides. The most stable iron oxide, α‐Fe 2 O 3 or hematite, is a promising material for sustainable hydrogen production via solar water splitting. The recent progress in understanding and overcoming the limitations presented by this material is reviewed by Sivula et al. on page 432 of this issue.
