Research Interests
Our research is currently centred around the design, preparation, and testing of energy materials, catalysts, and adsorbents. A primary focus is the application of energy materials to technologies such as fuel cells and electrolysers for clean power generation and green hydrogen production, and catalysts for converting carbon into useful and sustainable fuels and chemicals. Additionally, we utilise adsorbents for carbon capture technologies and water treatment for environmental applications. Overall, our goal is to enhance technology performance, reliability, cost-effectiveness, and sustainability.
We are particularly interested in the instrumentation and methods that underpin this research. We strive to understand materials and processes at every scale, from the atomic to the macroscopic. This often involves supporting investigations with in situ electron microscopy studies to understand the role of atoms in driving material properties, and advanced synchrotron experiments coupled with process analysis to understand structure-property correlations across material scales.
Furthermore, we are invested in understanding the impact of these materials at scale. For example, we assess the consequences on performance at the device, system, and ultimately, economic levels when a material's property or metric is improved. For instance, if we enhance a material's ion conductivity for electrolysers tenfold, what is the effect on the cost of the produced hydrogen? This understanding is crucial for identifying the factors that drive the reduction of costs of technologies and processes, making them viable for enabling other technologies or fields. It also helps in agenda-setting by determining if certain materials are worth developing and to what extent before diminishing returns are reached, and a step-change innovation is required to further advance a field.
Many of these processes are also relevant for space exploration. For example, the Martian atmosphere is rich in carbon dioxide, which could be harnessed to produce pure oxygen for sustaining life and fuels and chemicals for sustaining colonization. As such, one area we are looking to expand into is energy and chemical production for space exploration.
