Summary: Hematite is a promising catalyst for photoelectrochemical water splitting due to its stability, abundance, and low cost. However, the slow water oxidation kinetics and poor charge transportation have limited its practical application. To address these issues, a three-component heterojunction photoelectrode was designed by incorporating a visible light responsive metal-organic framework (MOF) and optimized plasmonic Ag nanorods into hematite nanostructures. The incorporation of MOF and Ag nanorods resulted in improved light harvesting and enhanced charge transport, leading to superior performance for hematite-based photoelectrochemical water oxidation.

Summary: In this study, conductive substrates of Ti3C2 and TiO2/Ti3C2 were prepared and utilized for the in-situ growth of hematite via electrophoretic deposition and hydrothermal methods. The TiO2/Ti3C2-hematite photoanode exhibited a significantly enhanced photocurrent density of 1.29 mA cm-2, which was 3.7 times higher than that of the FTO-hematite. This improvement was attributed to the improved interface property and the larger specific surface area provided by the layered TiO2/Ti3C2 conductive substrate.

Summary: This study demonstrates the fabrication of two-dimensional SnO2 nanosheet arrays and their application as electrodes for solar water oxidation. The nanosheets, when deposited on transparent electrodes, serve as substrates for the deposition of photoactive semiconductors, resulting in improved photoelectrochemical performance. The SnO2 nanosheets alone exhibit negligible PEC activity, suggesting that their enhanced performance is mainly due to their morphology and electronic effects. These findings provide a foundation for further research on efficient photoanode architectures for water splitting.

Summary: In this study, a preparation strategy for hematite phase-pure photoanodes was reported. The strategy involved a two-step annealing process to obtain high density hematite ultrathin nanoflakes and convert undesired iron oxide phases to a photoactive hematite layer.
