This PhD opportunity at the University of Sydney focuses on developing innovative catalytic air-gap electrochemistry methods for sustainable nitrogen fixation, inspired by natural lightning processes. The project aims to address the environmental impact of the Haber-Bosch process, which is responsible for a significant portion of global CO₂ emissions and energy consumption. By leveraging high-energy electrons in non-thermal plasma, the research seeks to activate inert nitrogen from air and drive radical reactions at air–water–catalyst interfaces, offering a greener alternative for fertilizer production.

The successful candidates will join a collaborative effort between the MMY group (catalysis) and the Jiang group (plasma chemistry), working within the Laboratory of Advanced Catalysis for Sustainability. The research involves both heterogeneous and homogeneous catalysis, materials and reactor design, and the study of how catalyst structure influences performance in electrochemical and radical-driven pathways. Students will gain hands-on experience with advanced characterization techniques such as chromatography, microscopy, and spectroscopy.

Two fully funded PhD positions are available as part of an ARC Discovery Project (2026-2029), covering tuition and stipend. Applicants should have a strong background in Chemistry and materials science, a 4-year undergraduate degree with First Class Honours or a research thesis, or a Master’s Degree by late 2025/early 2026. Prior research experience, preferably with a publication, is required, along with excellent English communication skills and a GPA above 3.4/4.0 (or >85/100 or top 10% in class). Only candidates graduating from a top 100 university worldwide (preferably top 50) will be considered.

Applications are accepted year-round, but international candidates should apply 3-6 months in advance and Australian candidates at least 2 months in advance. To apply, submit your CV via the provided Google form. Please ensure you meet all requirements before applying, and do not send email or platform enquiries.
