The number most likely refers to the scientific article "One-step synthesis of highly active cotton floc like ZnO–BiOI: Visible-light photocatalytic performance, recovery and degradation mechanism," published in the Journal of Solid State Chemistry , Volume 327 (2023).
Traditional photocatalysts like TiO₂ often suffer from a wide bandgap, limiting their efficiency to the ultraviolet spectrum. Heterojunction engineering—coupling two semiconductors with staggered band alignments—is a proven strategy to extend light response into the visible range. This paper focuses on the system. ZnO provides a robust, non-toxic framework, while BiOI, a p-type semiconductor with a narrow bandgap, serves as a visible-light sensitizer. 2. Materials and Methods
: The "cotton floc" morphology was confirmed using Scanning Electron Microscopy (SEM). Structural integrity and crystalline phases were verified via X-ray Diffraction (XRD).
