• In this work, we demonstrate the CoOOH/(Ti, C)-Fe 2 O 3 (CTCF) nanorods prepared by a facile approach as well as their implementation as photoanodes for photoelectrochemical (PEC) water splitting. The photocurrent density of CTCF photoanode is 1.85 mA cm −2 at +1.23 V vs. reversible hydrogen electrode (RHE), which is more than 20 times higher than that of pristine α-Fe 2 O 3 photoanode (0.08 mA cm −2 ). The incident-photo-to-current conversion efficiency, applied bias photo-to-current efficiency and transfer efficiency of CTCF photoanode reaches 31.2% at 380 nm (+1.23 V vs. RHE), 0.11% (+1.11 V vs. RHE), 68.2% (+1.23 V vs. RHE) respectively, which are much higher than those of pristine α-Fe 2 O 3 photoanode. Additionally, the longtime irradiation PEC water splitting of CTCF photoanode demonstrates its high stability at extreme voltage in NaOH (pH 14).
