“…As we all know, the V fb value of n-type semiconductor was approximately equal to the minimum potential of CB, and the V fb value of p-type semiconductor was approximately equal to the maximum potential of VB. [46,47] Therefore, for Fe 2 O 3 and FePO 4 , the CB positions (E CB ) were 0.50 and 0.22 eV vs. RHE, respectively; for FeOOH, [30] the VB positions (E VB ) was 2.12 eV vs. RHE. According to Equation ( 6), [48] for Fe 2 O 3 and FePO 4 , the VB positions (E VB ) were 2.63 and 2.57 eV vs. RHE; for FeOOH, the CB positions (E CB ) was À 0.07 eV vs. RHE.…”

Controlling the charge transfer pathway in semiconductors is an important method to improve charge separation efficiency and enhance photoelectrochemical activity. In this work, a Fe2O3/FePO4/FeOOH nanorod photoanode with stepped energy band structure is prepared by a hydrothermal and water bath method. The charge separation efficiency of the ternary heterojunction is higher than that of the traditional type II heterojunction, which might be due to the efficient cascade charge transfer and separation effect of the ternary stepped energy band heterojunction. The H2 and O2 evolution rates for photoelectrochemical water splitting of Fe2O3/FePO4/FeOOH photoanode are 0.247 and 0.111 μmol min−1, which is 2.15 and 1.95 times that of the Fe2O3/FePO4 photoanode, respectively. The incident photocurrent efficiency (IPCE) of Fe2O3/FePO4/FeOOH photoanode under 365 nm light irradiation is 1.5 and 1.8 times that of Fe2O3/FePO4 and Fe2O3/FeOOH photoanodes, respectively. This work provides an attractive strategy for solar energy conversion to construct efficient photoelectrochemical photoanode materials.

A platform for efficient photoelectrochemical (PEC) water splitting must fulfil different requirements: the absorption of the solar spectrum should be maximized in use for charge carrier generation. To avoid recombination, fast separation of charge carriers is required and the energetic positions of the band structure(s) must be optimized with respect to the water splitting reactions. In these respects, constructing tandem nanostructures with rationally designed nanostructured units offers a potential opportunity to break the performance bottleneck imposed by the unitary nanostructure. So far, quite a few tandem nanostructures have been designed, fabricated, and employed to improve the efficiency of PEC water splitting, and significant achievements have been realized. This review focuses on the current advances in tandem nanostructures for PEC water splitting. Firstly, the state of the art for tandem nanostructures applied in PEC water splitting is summarized. Secondly, the advances in this field and advantages arising of employing tandem nanostructures for PEC water splitting are outlined. Subsequently, different types of tandem nanostructures are reviewed, including core‐shell tandem nanostructured photoelectrode, the two‐photoelectrode tandem cell, and the tandem nanostructures of plasmon related devices for PEC water splitting. Based on this, the future perspective of this field is proposed.
