This project aims to develop and validate a solar-driven photocatalytic reactor model for quaternary wastewater treatment, based on a novel ZnO–g-C?N?–polydopamine (PDA) nanocomposite. The proposed photocatalyst is designed to degrade persistent micropollutants – such as pharmaceuticals and phthalates – commonly found in treated municipal wastewater, which are inadequately removed by conventional technologies. The research will focus on synthesizing and optimizing the photocatalyst, evaluating its performance under real wastewater conditions, and constructing a laboratory-scale reactor operating under natural or simulated solar irradiation. The project is aligned with the EU’s updated Urban Wastewater Treatment Directive, which mandates micropollutant removal and energy-efficient treatment processes. Expected results include three peer-reviewed scientific publications and a working laboratory model of the solar photocatalytic reactor. The outcomes will contribute to fundamental scientific knowledge in photocatalysis and hybrid nanomaterials, support future technology scale-up, and promote environmentally friendly solutions for sustainable water management. The project also supports capacity building by involving early-career researchers and contributes to Lithuania’s leadership in green innovation.
