In this work, we demonstrate the CoOOH/(Ti, C)-Fe2O3 (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-Fe2O3 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-Fe2O3 photoanode. Additionally, the longtime irradiation PEC water splitting of CTCF photoanode demonstrates its high stability at extreme voltage in NaOH (pH 14).

本论文利用一种温和的方法合成了CoOOH/(Ti, C)-Fe2O3(CTCF)纳米棒光阳极, 并对其光电解水性能进行了研究. 在可见光照和1.0 V偏压(相对可逆氢电极)条件下, CTCF光阳极产生的光电流密度为1.85 mA cm−2, 远高于传统的α-Fe2O3光阳极的光电流密度. 同时, 该电极在强碱性电解液中(pH 14)可以保持较长时间的稳定性.
