A Series of Cobalt bis(Thiosemicarbazone) Catalysts for Effective Photocatalytic Hydrogen Evolution Reaction

The Front Cover depicts photocatalytic hydrogen production in water using a series of cobalt complexes bearing redox non-innocent ligands as molecular catalysts and carbon dots as metal-free photosensitizers. After visible light irradiation, proton conversion into hydrogen was observed, with great activity (up to 570 TONs) and high stability. We are grateful to Dr. Sylvain Bertaina for his assistance in the design of the cover illustration. More information can be found in the Research Article by K. Ladomenou, A. G. Coutsolelos, M. Orio and co-workers.
