Abstract

A novel fire treatment was adopted to activate two types of hematite photoanodes (sol–gel thin films and hydrothermal nanowires), which successfully removed the surface trap states (surface hydroxyls) on hematite. An optimized photocurrent density of 2.63 mA cm−2 was observed at 1.23 V vs. RHE.
