Join us at the forefront of photocatalysis and sustainable materials research, where you will help develop innovative technologies that harness solar energy to create value from challenging waste streams.
About us
The Department of Chemistry and Chemical Engineering pushes the knowledge of chemistry and chemical engineering forward in a broad field of research and education. We offer an international environment, with scientific areas ranging from fundamental chemistry, health and medical technology, materials science, renewable energy, to chemical engineering processing, material recycling, nuclear chemistry, theory and modelling.
At the division of Applied Chemistry we primarily focus on applied research, that is, research aimed at addressing societal challenges and that is ready for implementation either immediately or in the near future. Examples of application areas include fossil-free fuels and energy systems, electronic devices, health and technology, the utilisation of fibres and forest-based materials, and various forms of catalysis.
The Ergang Wang group focuses on synthesis of organic semiconductors for organic electronics and photocatalysts for hydrogen generation and polymer degradation. Presently, the group consists of 1 Professor, 1 permanent researcher, 6 Postdocs and 2 PhD students.
About the research project
This PhD position is part of SPECTRA, a Horizon Europe EIC Pathfinder project bringing together Chalmers University of Technology (Sweden), Karlstad University (Sweden), Eindhoven University of Technology (Netherlands), Chalmers Industriteknik (Sweden), Cicci Research (Italy), and Antares Electrolysis (Italy). The consortium combines expertise in materials science, photocatalysis, modelling, optical engineering, reactor development, sustainability assessment, and industrial innovation to develop next-generation technologies for circular resource utilization. At Chalmers, the PhD project will focus on the development of advanced photocatalytic materials and processes for the selective conversion of plastic waste into valuable products. The work will include photocatalyst synthesis and characterization, photocatalytic reaction studies, product separation and purification, mechanistic investigations, and collaboration with European partners working on modelling, reactor engineering, and sustainability assessment. The successful candidate will join an international and interdisciplinary team addressing one of the most important sustainability challenges of our time.
Who we are looking for
The following requirements are mandatory:
