Applying advanced magnetic resonance methodologies to address critical challenges in the production and recycling of electrocatalysts for clean energy technologies.
Electrocatalysts such as Pt/C systems underpin fuel cells and electrolysers central to the UK’s Net Zero ambitions, yet translating laboratory performance to industrial manufacture remains a major hurdle. This project develops a powerful, multiscale NMR toolkit—combining relaxometry, fast field cycling (FFC), and pulsed field gradient diffusometry to generate a continuous, quantitative picture of molecular motion from nanoseconds to milliseconds and from molecular to micron length scales. By capturing dynamic processes such as adsorption, aggregation, and mass transport (phenomena often invisible to conventional structural characterisation) the work will provide new mechanistic insight into how electrocatalysts are manufactured, optimised and recycled.
Two focused proof-of-concept studies will demonstrate impact across the catalyst lifecycle: first, improving the stability and consistency of catalyst inks used in electrode manufacture; and second, optimising platinum group metal (PGM) recovery by characterising transport processes in industrial sorbents. The project is strongly embedded in industrial collaboration, with Johnson Matthey (JM) providing materials, technical expertise, and training placements. The partnership between Cambridge (advanced NMR), Southampton (electrocatalyst structure–function expertise), and JM (global electrocatalyst manufacture and recycling) ensures rapid translation from fundamental characterisation to practical process optimisation. By reducing waste in ink formulation, improving batch consistency, and enhancing the efficiency of precious metal recycling, the project directly advances both the Characterisation and Sustainability themes of the Hub, strengthening the UK’s capability in sustainable catalyst manufacture.
