Photocatalytic ceramic membrane: Effect of the illumination intensity and distribution

Journal of Photochemistry and Photobiology A: Chemistry, 2022
The principles and application of heterogeneous photocatalytic processes have gained wide attention, especially to the effectiveness of the process. In this work a mono and a multi-LED lamp are used to study the impact of the UV light intensity and distribution on the semiconductor surface during the degradation of organic compounds in water.

Boosting membrane interactions and antimicrobial effects of photocatalytic titanium dioxide nanoparticles by peptide coating. [PDF]

, 2023
Photocatalytic nanoparticles offer antimicrobial effects under illumination due to the formation of reactive oxygen species (ROS), capable of degrading bacterial membranes. ROS may, however, also degrade human cell membranes and trigger toxicity.
