Bismuth oxide (BiVO) is considered one of the most promising semiconductors for photoelectrochemical (PEC) water splitting due to its highly theoretical photocurrent of 7.5 mA cm. However, its sluggish kinetics and severe photocorrosion still hinder the real application of a large-area BiVO photoanode.

Article Synopsis
  • - The severe photocorrosion of cadmium sulfide (CdS) limits its use in solar hydrogen production, prompting the need for better protective strategies.
  • - A new hybrid overlayer combining defective Ni-MOF and NiO nanoparticles is developed and applied to TiO/CdS heterojunctions, resulting in a photoanode that significantly boosts photocurrent density.
  • - The hybrid overlayer enhances performance by isolating CdS from the electrolyte, acting as a cocatalyst, passivating surface defects, and improving charge transfer, demonstrating notable stability with 70% photocurrent retention after 11 hours.
