“Enhanced Photocatalytic Degradation of Ciprofloxacin by a Piezoelectric NaNbO3-FeOOH Nanocomposite”

https://pubmed.ncbi.nlm.nih.gov/38112438

The study reports the development of a piezoelectric nanocomposite of NaNbO~3~ and FeOOH that exhibits enhanced photocatalytic degradation of a pharmaceutical pollutant, ciprofloxacin, and oxygen evolution through water splitting, due to the coupling of macroscopic spontaneous piezoelectric polarization and a built-in electric field, resulting in fast separation/migration of charge carriers from the bulk to the surface.
