Stable Hematite Nanosheet Photoanodes for Enhanced Photoelectrochemical Water Splitting

Stable Hematite Nanosheet Photoanodes for Enhanced Photoelectrochemical Water Splitting

A vertically grown hematite nanosheet film modified with Ag nanoparticles (NPs) and Co–Pi cocatalyst exhibits a remarkably high photocurrent density of 4.68 mA cm−2 at 1.23 V versus RHE. The Ag NPs leads to significantly improved light harvesting and better charge transfer, while the Co–Pi facilitat...

Zusammenfassung:A vertically grown hematite nanosheet film modified with Ag nanoparticles (NPs) and Co–Pi cocatalyst exhibits a remarkably high photocurrent density of 4.68 mA cm−2 at 1.23 V versus RHE. The Ag NPs leads to significantly improved light harvesting and better charge transfer, while the Co–Pi facilitates a highly stable oxygen evolution process. This photoelectrode design provides more efficient photoelectrochemical systems for solar‐energy conversion.
