This paper describes a promising film based on the dumbbell‐shaped CaBi 2 O 4 nanostructure that is applied in photoelectrochemical (PEC) water splitting as a photoelectrode for the first time. The morphology and microstructure of CaBi 2 O 4 were characterized in detail. PEC measurements showed that the dumbbell‐shaped CaBi 2 O 4 nanostructure film, on the basis of the optimal hydrothermal time, exhibited higher photoelectrochemical activity, as the photocurrent density reached up to 1.19 mA cm −2 . The remarkable PEC performance may stem from excellent light absorbance and efficient charge–hole pair separation and collection. This research indicates that the dumbbell‐like CaBi 2 O 4 nanostructure film has enormous potential in PEC water splitting.
