In this work, a thin Fe<jats:sub>2<\/jats:sub>TiO<jats:sub>5<\/jats:sub> layer was decorated on nanostructured hematite nanoflake and nanocoral photoanodes (by thermal oxidation of iron foils) by a facile water\u2010based solution method. Photoelectrochemical measurements show that the Fe<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub>\/Fe<jats:sub>2<\/jats:sub>TiO<jats:sub>5<\/jats:sub> heterostructure exhibits an obvious enhancement in photoelectrochemical water oxidation performance compared to the pristine hematite. For example, at 1.23\u2005V versus the reversible hydrogen electrode (V<jats:sub>RHE<\/jats:sub>) in 1\u2009<jats:sc>m<\/jats:sc> KOH under AM\u20091.5\u2009G (100\u2005mW\u2009cm<jats:sup>\u22122<\/jats:sup>) illumination, a 4\u20138\u00d7 increase in the water oxidation photocurrent is achieved for Fe<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub>\/Fe<jats:sub>2<\/jats:sub>TiO<jats:sub>5<\/jats:sub>, and a considerable cathodic shift of the onset potential up to 0.53\u20130.62\u2005V<jats:sub>RHE<\/jats:sub> is obtained. Moreover, the performance of the Fe<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub>\/Fe<jats:sub>2<\/jats:sub>TiO<jats:sub>5<\/jats:sub> heterostructure can be further improved by decoration with a SnO<jats:sub><jats:italic>x<\/jats:italic><\/jats:sub> layer.
