Randomized trial demonstrates enhanced photocatalytic activity in synthesized films, suggesting improved material design strategies.

The research aims to develop stable and efficient photocatalytic materials using TiO2 and SrTiO3 thin films.
Single-layer and sandwich-like TiO2-SrTiO3 coatings were synthesized on FTO using liquid phase deposition.
Films were characterized by XRD, FIB-SEM, ToF-SIMS, impedance spectroscopy, and photoelectrochemical measurements.
Photocatalytic activity was evaluated through terephthalic acid hydroxylation, nitroaromatic reduction, and hydrogen evolution.
Sandwich-like structures improved hydrogen generation rate, surpassing plain films by almost three times.
Enhanced charge separation and directional carrier transport were noted at engineered oxide interfaces.
Liquid phase deposition enabled production of homogeneous and stable photocatalytic films.

Adamowicz et al. (2026) studied this question.
