Beschreibung

Solar-driven photocatalysis is a promising strategy for sustainable water purification. In this project, the student will investigate PDA-modified TiO₂ hydrogel reactors for the photocatalytic degradation of organic pollutants under light irradiation. Polydopamine-modified TiO₂ nanoparticles will be incorporated into PVA-based hydrogel matrices to construct floating photocatalytic reactors with enhanced light absorption, pollutant contact, and water-treatment performance.

The work will focus on evaluating the degradation performance of different reactor systems, including TiO₂, PDA- TiO₂, PVA- TiO₂, and PVA-PDA/ TiO₂ hydrogels. Various model pollutants, such as organic dyes and antibiotics, may be used to assess the photocatalytic activity. In addition, tests using real water samples, for example outdoor pond water, may be conducted to explore the practical applicability of the hydrogel reactor.

The student will be involved in material preparation, photocatalytic degradation experiments, UV-Vis analysis, kinetic evaluation, and basic material characterization. The aim of this project is to understand how PDA modification and hydrogel integration influence pollutant degradation efficiency, reaction kinetics, and the potential application of hydrogel-based photocatalytic reactors for solar-driven water purification.
