Abstract
α-Fe(2)O(3) with suitable band structure, good chemical stability, and easy preparation, is a potential photoanode material. However, the key to enhance the performance of α-Fe(2)O(3) photoanode is to improve the transport characteristics of bulk carriers. It is expected to form a Schottky barrier to improve the carrier separation efficiency by embedding metal nanoparticles into the matrix, but the process is still challenging. Herein, a strategy of forming the Schottky barrier is shown to improve bulk carrier transport dynamics by embedding laser-generated Pt nanocrystals in α-Fe(2)O(3) photoanode, which achieves photocurrent densities of up to 1.16 mA cm(-2) at 1.23 V(RHE) (from original 0.21 mA cm(-2)). This work provides another way to promote the carrier transfer and separation of α-Fe(2)O(3), which is of great significance to improve the photoelectrochemical water splitting performance.
