• Power up: The photoelectrochemical performance of hematite in a water‐splitting device was improved significantly through surface modification with amorphous NiFeOx (see graph showing the large cathodic shift observed; FTO=fluorine‐doped tin oxide). The measured photovoltage increased from 0.24 to 0.61 V, which yielded a record‐low turn‐on potential of 0.62 V (versus the reversible hydrogen electrode, RHE).
