I am a Material Chemist working in the field of electrocatalysis and electrochemical storage and conversion technologies. In brief, our research is focused on developing new materials and fundamental understanding to develop clean, sustainable and green technologies for a Net Zero future. More specifically, our research group is focused on the design, discovery and characterisation of new materials and catalyst motifs. In particular, we are interested in characterising these materials in fuel cells and electrolysers. This involves nanoparticle synthesis as well as extensive materials and electrochemical characterisation. Our work is highly collaboratively, and we currently work theoreticians, beamline scientists, microscopists, engineers and more.
Chemistry & Society 2 - In particular, we focus on semiconductors and solar cells in my portion of the course. We seek to explore 1) how a solar cell works, 2) how solar cells are manufactured in industry and research labs todays, and 3) how to understand the performance of a solar cell (e.g. how efficient is a solar cell?). This course is an excellent opportunity for students to learn about technologies that is essentail for the globe to reduce our carbon emissions and meet renewable energy targets.
Frontiers (MChem) & Energy Materials (MSc Advanced Materials). In this course we discuss next-generation energy storage and conversion technologies. Specifically, we discuss the challenges and opportunities of energy production technologies (from fossil fuels to renewables to green hydrogen). Primarily, we focus on energy technologies that provide transformative routes to large-scale decarbonisation of energy. From lithium ion batteries, to supercapacitors and fuel cells, we will discuss how these technologies work and the materials that are essential to their operation. This course provides students with the required knowledge to understand how our future energy and electricity requirements will meet Net Zero requirements.
Bulk Characterisation (MSc Advanced Materials). This course provides an in depth discussion to enable students to gain an expert understanding of numerous bulk characterisation techniques. Specifically, in my portion of the class I will teach x-ray diffraction (XRD) and secondary electron microscopy (SEM). The course is designed to incorporate numerous research examples so that students become familiar with interpretating and assessing data in industry and academia.
Physical Chemistry Labs (Second year). All second year Chemists join us to apply our physical chemistry knowledge in the laboratory. From kinetics, thermodynamics and surface chemistry we give students a broad and wide ranging experience of applying theory. Beyond our work together in the lab, learning to produce high quality figures and interpret findings is an essential learning outcome for your future careers - no matter which profession you pursue.
BSc, MChem and MSc Project Supervision. Interested in understanding materials and how we can apply our knowledge for a green and sustainable future? Research projects are available for motivated students who want to learn to synthesise advanced functional nano-materials as well as materials and electrochemical characterisations.

Overview
Research in the King Lab is focused on the design, synthesis and characterisation of materials and catalysts with interesting and unique properties for applications in renewable energy conversion and storage technologies. Our work is motivated by the need to design a more sustainable and green future. Our research is highly collaborative, engaging with numerous industrial and academic partners and lies at the interface of chemistry, materials science and physics.
Primary Research Themes
Research Background
Electrocatalysis are central to numerous energy conversion and storage technologies. Our approach is to explore fundamental understanding of materials and catalysts to drive the discovery of catalysts with enhnaced activity, selectivity and durability.
Interested in working with us?
We are always interested in hearing from highly motivated students, researchers as well as industry who would like to discuss research opportunities and collaborations.
