The Faculty of Sciences of the University of Porto (FCUP) is recruiting a postdoctoral researcher for the CATCH project, focused on the recovery and application of char and ferrospheres from coal fly ash to green energy sources. This position is based in the Department of Geosciences, Environment and Spatial Planning, and is funded by the Innovation and Digital Transition Program (COMPETE 2030), the European Regional Development Fund (FEDER), and co-financed by the Foundation for Science and Technology (FCT).

The successful candidate will participate in the development and execution of the research project, undertaking scientific and technical activities such as sampling, materials characterization, char concentration and transformation, electrochemical characterization of electrocatalysis, custom-designed membrane development, cell construction, and ORR (oxygen reduction reaction) testing in continuous mode. The work aims to develop efficient beneficiation processes for char and ferrospheres, utilizing gravimetric, impaction, sieving, electrostatic, and magnetic methods. Analytical techniques include proximate analysis, TOC and carbon forms, XRF, XRD, Raman spectroscopy, petrographic analysis by reflected light microscopy, TEM, and SEM-EDS. The researcher will also modify char by thermal means, doping with heteroatoms, and chemical treatment, including demineralization and catalytic/microwave graphitization.

Additional responsibilities include calculating material recovery and purity, characterizing thermally modified materials, monitoring cell construction and performance, supporting project management, preparing reports in English, participating in project meetings, assisting in the supervision and training of students, and disseminating results. There is also the possibility of contributing to teaching activities at FCUP, up to four hours per week on average.

The position offers a monthly salary of €2,351.53 for a duration of 22 months, with exclusive dedication. Applicants must hold a PhD in Geosciences obtained within the last five years and demonstrate expertise in materials characterization, separation and concentration techniques, and thermal/chemical modification of char and ferrospheres. A strong publication record and alignment with the project objectives are essential. Applications must be submitted online, including all required documents, within the specified application window. The selection process involves evaluation of scientific and academic career, with possible interviews for top candidates. Only those scoring 70 points or higher are eligible for hiring.

FCUP is committed to non-discrimination and equal access, welcoming applications from all qualified candidates. The application period runs from December 10, 2025, to December 23, 2025. For further details and to apply, visit the official call webpage.
