Abstract

Abstract : A (012) plane oriented hematite film with secondary growth of organized microcrystals showed promising photoelectrochemical efficiency compared with a randomly oriented film. Abstract : To improve the optoelectronic properties of hematite film as a photoanode, hematite film was orientated on the (012) plane by the secondary growth of organized microcrystals. The resultant film showed promising photoelectrochemical effects compared with a randomly oriented one, with a maximum photocurrent of 0.8 mA cm −2 at 1.23 V vs. RHE under the illumination of 1 sun.
