Silver Nanoparticles Influence on Photocatalytic Activity of Hybrid Materials Based on TiO2 P25

Abstract EN

The aim of the present study consists in the obtaining of a hybrid material film, obtained using TiO2 P25 and silver nanoparticles (AgNPs).

The film manufacturing process involved realization of physical mixtures of TiO2 P25 and AgNPs dispersions.

The size distribution of the AgNPs proved to be a key factor determining the photodegradation activity of the materials measured using methyl orange.

The best result was 33% degradation of methyl orange (MO) after 150 min.

The second approach was the generation of AgNPs on the surface of TiO2 P25.

The obtained hybrid material presents photocatalytic activity of 45% MO degradation after 150 min.

The developed materials were characterized by UV-VIS, SEM, and DLS analyses.
