The environmental challenges we face require the synergy of skills from diverse scientific communities. In the context of the global reduction of the carbon footprint, which notably involves CO2 treatment, the production of green energy and hydrogen, and the synthesis of organic compounds now assisted by photo- and electro-assisted processes, electrochemists and photochemists are at the forefront, both in the development of efficient molecular systems and catalysts, and in understanding the mechanisms involved in photochemical and photoelectrochemical processes. Building on the RT PES 2.0, which brings these two communities together, and following a first Thematic School organized in 2021 that gathered 55 participants, this second edition aims to provide research personnel (doctoral students, researchers and research professors, engineers) with the fundamentals and more advanced theoretical and experimental tools necessary to address these challenges.

The school will take place over a one-week period (5 days, Monday to Friday, with arrival on Sunday evening) at a venue suitable for lectures and workshops, and will provide accommodation for all participants. This format will facilitate interaction between the teaching researchers and the participants, particularly young people, to answer questions of all kinds, which is more difficult with conference-style formats. The school will include practical workshops allowing for live demonstrations and introductory sessions using equipment brought on-site. The workshops will also address implementation issues through discussions focused on experimental practice in both disciplines. The school format will contribute to the training of doctoral students, as it will be recognized as such by doctoral schools, and to the training of researchers and engineers, with a significant proportion of CNRS staff.
