hydrogenase mimics, hydrogen production, hydrogen activation, electrocatalyst, photocatalyst
Hydrogen is currently considered as a promising post-oil energy carrier owing to its remarkable properties such as its environmental neutrality, clean aerobic combustion with a high specific energy value, and its ability to be stored in large quantities. In this context, great attention has been paid to proteins called hydrogenases, which are known to serve as highly active catalysts for H2 evolution in Nature. In the last years, a large variety of hydrogenase mimics have been developed to test their electrocatalytic or photocatalytic ability for H2 production and uptake.The session will cover all topical issues of hydrogenase research, e.g. functional models of [Fe], [FeFe] and [NiFe] hydrogenases, mononuclear earth abundant hydride complexes (Co, Ni, Cu…), multicomponent systems with commonly used organometallic photosensitizers of either Ru, Re, Rh, or Ir, and [FeFe] hydrogenase mimics bearing sensitizer窶田atalyst dyads, in which a light harvester is covalently linked to. The 2.5 days session will be divided in several topics like synthesis of hydrogenase mimicks, (photo)chemical mechanisms of catalytic hydrogen evolution reactions, synergistic effects by combining molecular systems with matrix material, electrode materials and artificial photosynthetic systems, theoretical calculations and investigation of hydrogenase models, to mention a few. This session is a wonderful opportunity to get a better understanding on how active site synthetic analogues of hydrogenases are made, on the mechanisms of their performance at a molecular level and how economically viable electro/photocatalytic systems will be designed.
