The abundance of solar energy on Earth and the natural photosynthesis in plants has motivated extensive worldwide research into photon capture by synthetic materials and conversion into storable fuels. This remains focused largely on the development of materials for solar fuel production that are: (i) efficient in converting photons to chemical product(s), (ii) inexpensive to fabricate and (iii) robust. However, despite substantial progress in material development, the question ‘How might an industrial scale, efficient photoelectrochemical reactor system ultimately look?’ still remains unanswered. This will remain so until the performance, durability and cost of scalable reactor demonstration units are understood from the atomic to the industrial scale, via modelling, design, fabrication and characterisation. Development of up-scaled reactors is a multidisciplinary challenge, involving material science, (photo)electrochemistry, electrochemical engineering and optics, supplemented by numerical modelling of the complete system to guide its design and optimisation. These many considerations need to be addressed simultaneously and will be the focus of this symposium.

I'm an Associate Professor in the Department of Chemical Engineering at Imperial College London (ICL). My principal interests and expertise are in the science and engineering of electrochemical energy conversion, CO2 reduction, and separation processes for industrial effluent treatment and material recycling. After obtaining my MSci degree in Physics at ICL in 2007, I moved to the Department of Chemical Engineering to carry out PhD studies in electrochemical wastewater treatment through heavy metal recovery. I subsequently conducted multiple postdoctoral research projects in the same department, including in photoelectrochemical solar fuel production, waste management by electrochemical treatment of waste streams and valorisation of CO2 via conversion into fuels. Academic research projects in my group are aimed at solving industrial problems through both experimental and numerical modelling investigations.
Fatwa Abdi is an Associate Professor at the School of Energy and Environment, City University of Hong Kong. Until July 2023, he was a group leader and the deputy head of the Institute for Solar Fuels, Helmholtz-Zentrum Berlin (HZB). He obtained his PhD (cum laude) in Chemical Engineering from TU Delft, the Netherlands, in 2013. He was the recipient of the Martinus van Marum prize from the Royal Dutch Society of Sciences and Humanities. His research focusses on the development of novel (photo)electrode materials as well as engineering and scale-up of devices for solar fuels and chemicals conversion.
Doing my BSc/MSc in Physics and PhD in an interdisciplinary program crossing the disciplines like Chemical Engineering, Nanotechnology, and Electrochemistry made me who I am today – a scientist who enjoys the challenge of multifaceted research.
I enjoy doing basic research in order to solve applied tasks. This explains my research interest in fundamental physical chemistry, e.g. oxidation and dissolution of metals and semiconductors, electrocatalysis, and electrochemistry at modified interfaces but also electrochemical engineering, e.g. development and optimization of catalyst layers in fuel cells and water electrolyzes.
Progress in basic research is often a direct outcome of previous achievements in experimental instrumentation. Hence, a significant part of my interest is in the development of new tools, e.g. electrochemical on-line mass spectrometry, gas diffusion electrode approaches, and high-throughput screening methods.
Sixto Giménez (M. Sc. Physics 1996, Ph. D. Physics 2002) is Associate Professor at Universitat Jaume I de Castelló (Spain). His professional career has been focused on the study of micro and nanostructured materials for different applications spanning from structural components to optoelectronic devices. During his PhD thesis at the University of Navarra, he studied the relationship between processing of metallic and ceramic powders, their sintering behavior and mechanical properties. He took a Post-Doc position at the Katholiek Universiteit Leuven where he focused on the development of non-destructive and in-situ characterization techniques of the sintering behavior of metallic porous materials. In January 2008, he joined the Group of Photovoltaic and Optoelectronic Devices of University Jaume I where he is involved in the development of new concepts for photovoltaic and photoelectrochemical devices based on nanoscaled materials, particularly studying the optoelectronic and electrochemical responses of the devices by electrical impedance spectroscopy. He has co-authored more than 80 scientific papers in international journals and has received more than 5000 citations. His current h-index is 31.
