In this study, I discuss strategies to enhance the charge transport efficiency of hematite for more effective water splitting. Hematite is a promising photoactive material due to its affordability, water stability, and high theoretical solar-to-hydrogen conversion efficiency. However, its inherent limitations in conductivity and short hole diffusion length hinder widespread use as a photoanode material in water splitting. To address these challenges, I propose a straightforward approach focusing on the entire transport process, from the photoanode to the co-catalyst. The low conductivity is mitigated by creating a porous structure and implementing efficient doping. Additionally, poor contact between the photoanode and cocatalyst is resolved by introducing an organic hole transport layer (HTL). The optimized porous photoanode, prepared with optimal doping conditions and the HTL, demonstrates a maximum photocurrent density of 4.7 mA cm-2 at 1.23 VRHE, attributed to enhanced surface reaction kinetics. This study represents a significant breakthrough in substantially improving the poor PEC performance of hematite-based photoanodes, particularly addressing the short-hole diffusion pathway issue through optimal co-doping and nanostructuring.
