Summary: This study demonstrates the use of aluminum ferrite (AFO) as a stable solar absorber in photoelectrochemical cells, showcasing its attractive performance. AFO thin-film photoelectrodes composed of vertically oriented nanosheets exhibit a photocurrent density of +0.78 mA.cm(-2) at 1.23 V vs. RHE, with a U-onset close to the flat band potential of 0.5 V vs. RHE in the presence of hole scavengers. AFO also exhibits rare coincidence between U-onset and flat band potential for solar water splitting, along with other favorable optoelectronic properties and carrier lifetimes, suggesting its great potential for photoelectrochemical cell applications.

Summary: Constructing heterostructures, such as the intercrossed heterostructure of Bi2S3 nanosheets on hydrogen-treated TiO2 nanorods, plays a critical role in improving the photoelectrochemical performance. Hydrogen treatment enhances charge separation and narrow the band gap, resulting in a higher PEC performance in H-TiO2 compared to bare TiO2. The intercrossed heterostructure of Bi2S3/H-TiO2 achieves a significantly higher photocurrent density under visible light irradiation and benefits from efficient electron transfer and charge separation.
