The electrochemical conversion of carbon dioxide (CO2) into valuable chemicals and fuels represents a promising strategy to address climate change while creating sustainable manufacturing pathways. Powered by renewable electricity, CO2 electrolysis can transform waste carbon into products such as carbon monoxide, formate, ethylene, ethanol, and other industrial feedstocks, contributing to a circular carbon economy. However, widespread deployment of this technology is currently limited by challenges including insufficient catalyst activity and selectivity, poor long-term stability, and low system efficiency at industrially relevant operating conditions.
This PhD project aims to advance next-generation CO2 electrolysis technologies through the combined development of high-performance electrocatalysts and efficient electrolyser systems. The research will focus on understanding the fundamental mechanisms governing CO2 reduction reactions and translating this knowledge into practical device designs capable of achieving high conversion efficiency and product selectivity. The project aligns with Australia\u2019s ambitions to achieve net-zero emissions while strengthening its emerging clean energy and advanced manufacturing sectors.<\/p>\n\n\n\n

      Significance<\/p>\n\n\n\n

      This project addresses one of the most important challenges in the global transition to a low-carbon economy: transforming CO2 from a waste product into a valuable resource. By combining catalyst innovation with advanced electrolyser engineering, the project will contribute to the development of efficient and scalable CO2 utilisation technologies capable of producing sustainable fuels and chemicals using renewable electricity.
      The research will generate new knowledge in electrocatalysis, electrochemical engineering, and energy conversion while supporting Australia\u2019s net-zero emissions targets and clean technology priorities. The outcomes may enable future manufacturing opportunities in sustainable chemicals, renewable fuels, and carbon-neutral industrial processes. Furthermore, the project will provide advanced training in materials science, electrochemistry, and device engineering, preparing the successful candidate for a career in the rapidly growing fields of renewable energy and carbon management.<\/p>\n\n\n\n
