Photocatalytic properties of hybrid materials based on multicharged polymer matrix with encored TiO2 and noble metals (Pt, Pd or Au) nanoparticles

In this article, we report a synthesis of new nanocomposites included TiO2 into multicharged polymeric matrix and covered with noble metals (Pt, Pd or Au) for the photocatalytic application. The photocatalytic activity investigation in reaction of methylene blue degradation revealed that all obtained nanocomposites demonstrate the enhanced photocatalitic ability compared to pure TiO2: under UV (24 °C) and solar light (-2 °C). The morphology and catalytic properties of the nature composites depends on noble metals. The kinetic speed value of photodegradation was found to be increased in the following sequence: TiO2 < TiO2-NPst ≈ Pd-TiO2@NPSt < Pt-TiO2@NPSt≈Au-TiO2@NPSt.
