Device design and in-situ characterisation for efficient solar-driven synthesis of valuable chemicals Chen Han 1,2 , Xiaojing Hao 2 , Rose Amal 2 , Erwin Reisner 1 1 Yusuf Hamied Department of Chemistry, University of Cambridge, Cambridge, UK, 2 School of Chemical Engineering, University of New South Wales, Sydney, Australia Converting solar energy into chemicals and fuels through photo/electrocatalytic processes is challenging but holds significant potential for advancing sustainable development. Catalysts play an important role in these processes, and we have rationally designed catalyst materials to achieve high performance and cost-effectiveness. To deepen our understanding of catalytic mechanisms, several in-situ characterisation techniques have been employed to study catalysts under working conditions, providing valuable insights into both the materials and the reaction pathways. Additionally, we have innovated configurations of solar- driven devices and integrated suitable solar materials into photoelectrodes, aiming to optimally maximise and balance optical, electrical, and catalytic gains. We will illustrate these with our recent progress on the solar-powered synthesis of carbon-based products and
