Thanks to everyone for participating in the recent COST Action CM1202 Tarragona Training School and the Meeting of Working Groups 1 and 2 in Tarragona, Spain, 11- 14 April 2016, kindly hosted by Prof. Antoni Llobet, Institute of Chemical Research of Catalonia (ICIQ)

The meeting has served for elaborating networking between the Action members and nurture scientific discussions and future collaboration work. Achievements of the previous year have been discussed.

23 early career investigators took part in the training school organised by ICIQ and gained experience by discussing both theory and experiments.

Subsequent to the Training School, other experienced members of the network joined the event for a dedicated WG1/WG2 meeting.The development of SPCs for hydrogen production and water splitting presents a new, ambitious and interdisciplinary task, which addresses both fundamental scientific questions and – in the long run – important and imminent societal needs. The focus of WG 1 Synthesis and Photocataysis is to generate efficient strategies towards stabilization of the catalytic centers (both for proton reduction and water oxidation) in all required redox states within the ligand scaffold provided by the SPC. This presents a central aspect, since well-stabilized catalytic centers present an indispensible prerequisite for long-term operating catalytic systems. Device integration will immobilize hydrogen- and oxygen-evolving SPCs developed in WG1 on large-surface area transparent conducting oxides and semiconductors as well as in membranes. Thereby, building on the results of WG1, novel concepts for integration of SPCs into functional photocatalytically active electrodes are to be developed and characterized both photophysically and photocatalytically and theoretical tools to describe electronic states induced upon binding and their correlation with photoinduced electron transfer and catalytic properties are required.

Thanks again to everyone for your valuable input and especially, to Prof. Toni Llobet and Judit Martinez, ICIQ, for their great and smooth organisation!
