Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Power up</bold>: The photoelectrochemical performance of hematite in a water‐splitting device was improved significantly through surface modification with amorphous NiFeO_{<italic>x</italic>} (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).<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4t7bv3v8" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
