This doctoral position at KTH Royal Institute of Technology offers an exciting opportunity to contribute to the development of sustainable technologies for carbon utilization. The project centers on the thermal catalytic conversion of CO2 to solid carbon, a cutting-edge approach aimed at transforming captured carbon dioxide into valuable carbon materials for energy storage and industrial applications. The research integrates materials science, chemical reaction engineering, and process electrification, with a strong emphasis on experimental work in catalyst development, reactor design, and process operation. Advanced process modeling using Aspen Plus will support the experimental efforts, enabling a comprehensive understanding of both fundamental reaction mechanisms and practical system performance. As a doctoral student, you will join a dynamic, international research team at KTH, collaborating with industrial partners through national innovation programs. The project provides access to state-of-the-art laboratories for catalysis and materials characterization, as well as advanced analysis tools. You will work closely with experienced researchers specializing in CO2 utilization and sustainable process development, benefiting from KTH’s leading research environment and strong industrial partnerships. Supervision will be provided by Docent Weihong Yang and Professor Pär Jönsson, both recognized experts in the field. The position is based in Stockholm, Sweden, and is part of KTH’s commitment to advancing the transition towards a sustainable society through education, research, and innovation. The university offers a creative and dynamic environment, attractive employee benefits, and a strong focus on equality, diversity, and equal opportunities. Eligibility requirements include a second cycle degree (such as a master’s) or equivalent, with substantial coursework in relevant fields. Candidates must have experience in catalysis, thermochemical processes, or process modeling (Aspen Plus), and demonstrate strong English communication skills (spoken and written), with proficiency equivalent to English B/6. Selection will prioritize motivation, independence, collaboration skills, professionalism, and analytical ability. Applicants must submit a complete application including CV, application letter, diplomas, grades, language certificates, representative publications or technical reports, and two recommendation letters. The position offers full-time employment for up to four years, with a monthly salary according to KTH’s doctoral student salary agreement and comprehensive employee benefits. Applications must be submitted through KTH’s recruitment system by January 13, 2026. For further information, contact the supervisors via the provided email addresses. Join KTH and contribute to pioneering research in sustainable carbon technologies, while developing your skills in a world-class academic environment.

This PhD position at KTH Royal Institute of Technology offers an exciting opportunity to work on the development of bio-graphene materials for advanced lithium–sulfur (Li–S) battery applications. The project is situated within the third-cycle subject of Materials Science and Engineering and aims to create a scalable and sustainable process for converting biochar into high-performance three-dimensional bio-graphene. The research will utilize Fe-catalyzed graphitization, molten-salt templating, and precise control of residual iron species to produce materials with high electrical conductivity, hierarchical porosity, and tailored polar active sites. These innovations are expected to significantly enhance sulfur utilization, enable lean-electrolyte operation, and improve long-term cycling stability in Li–S batteries. The doctoral student will join a dynamic international research environment at KTH, collaborating closely with industrial partners through national innovation programs. Access to state-of-the-art laboratories for catalysis, materials synthesis, and advanced characterization is provided, and the student will work alongside experienced researchers specializing in bio-graphene and battery technologies. Supervision will be provided by Docent Weihong Yang and Professor Pär Jönsson, both recognized experts in the field. The position is fully funded with a monthly salary according to KTH's doctoral student salary agreement, and includes full employee benefits. The employment is for up to four years full-time, with the possibility of renewal according to Swedish regulations. Applicants must hold a second cycle degree (such as a master's) or have completed at least 240 higher education credits (with at least 60 at the second-cycle level), or possess equivalent qualifications. Required experience includes carbon materials synthesis and processing, particularly catalytic graphitization and/or templating approaches. Excellent English communication skills, both written and spoken, are mandatory, with proof of proficiency equivalent to English B/6. The selection process emphasizes motivation, goal orientation, perseverance, the ability to work independently and collaboratively, and strong analytical skills. To apply, candidates must submit a complete application through KTH's recruitment system by the deadline of April 2, 2026. Required documents include a CV, application letter, diplomas, grades, language certificates, and representative publications or technical reports. All documents must be certified and translated into English or Swedish if not originally issued in these languages. The position offers a creative and dynamic environment with excellent working conditions, attractive benefits, and a commitment to equality, diversity, and equal opportunities.
