Jo Humphrey

Higher Research Scientist

Jo joined NPL’s Electrochemistry Group in 2016, after completing both an MSci in Chemistry and PhD in Electrochemistry at the University of Bristol. Her Masters’ research investigated the use of non-boron doped diamond powders as electrocatalyst supports for use in fuel cell technologies, while her PhD research looked into the application of bimetallic nanocatalysts for the electrochemical interconversion of CO2 and liquid fuels.

During her time at NPL, she has primarily been involved in the technical delivery of the CritCat, a Horizon 2020 project which aims to identify and screen materials for electrocatalytic hydrogen evolution, with a primary focus on catalysts based on earth-abundant elements. This has required the development of robust electrochemical test protocols for existing and novel catalyst candidate materials, as well as the use of in situ Raman spectroscopy techniques to characterise materials under operating conditions, providing valuable insight into the identity and stability of the active catalysts.

Areas of interest

Jo has a broad range of research interests within the field of electrochemistry for renewable energy applications. These include, but are not limited to:

  • Electrocatalysis for energy conversion and storage, primarily for fuel cells, electrolysers and CO2 reduction applications
  • Electrocatalyst structure-activity relationships
  • Catalytic reactivity of noble metal, alloy, and transition metal nanomaterials
  • Synthesis and testing of colloidal nanoparticles as supported nanoparticle composites
