Lickety-split: A dumbbell-shaped CaBi₂O₄ nanostructure film is hydrothermally prepared and used as a photoelectrode for photoelectrochemical water splitting. This photoelectrode exhibits a high photocurrent density of 1.19 mA cm⁻². The remarkable performance may be attributed to improved light absorption, an ideal band gap value, and efficient charge–hole pair separation and collection.
