New photoanodes built from Fe 2 O 3 /NiO heterostructures were successfully prepared, and their morphologies and structures were systematically characterized by SEM, XRD, TEM, and HRTEM. The photoelectrochemical (PEC) properties of the heterostructures, including transient photocurrent density versus time ( I – t ) curves, photocurrent versus potential ( I – V ) curves, and incident‐photon‐to‐current efficiency (IPCE) curves, were also researched in depth. The p–n heterostructure composed of NiO and Fe 2 O 3 results in the improvement of electron transfer between Fe 2 O 3 and NiO.
