Construction of an efficient hole migration pathway on hematite for efficient photoelectrochemical water oxidation
Feng Li,Jing Li,Lili Gao,Yiping Hu,Xuefeng Long,Shenqi Wei,Chenglong Wang,Jun Jin,Jiantai Ma +8 more
TL;DR: In this paper, a hole migration pathway was constructed by integrating the co-catalyst (NiOOH) onto the homojunction structured Fe2O3 coating on F-doped α-Fe 2O3 nanorods, and the resulting photoanode exhibited higher photocurrent density (3.4-fold higher than pristine Fe 2O 3) and lower onset potential (0.61 VRHE) than most reported hematite-based photoanodes.
