Nature Communications, Published online: 18 May 2026; doi:10.1038/s41467-026-73161-6 Single-atom catalysts offer high efficiency for hydrogen evolution, but control of metal–support interactions remains challenging. Here, the authors report a rhodium single-atom catalyst platform enabling continuous tuning of metal–support frontier orbital interactions via anion-engineered supports.
