Abstract

Abstract: New photoanodes built from Fe2 O3 /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 Fe2 O3 results in the improvement of electron transfer between Fe2 O3 and NiO. Abstract : New Fe2 O3 /NiO heterostructures have been successfully synthesized. Variation of the quantity of NiO can significantly affect their microstructures and photoelectrochemical properties.
