Ligand tunability versus condition optimization: A guide into structure-activity/stability nexus and mechanistic insights into photoinduced hydrogen evolution using hexacoordinated cobalt complexes. This is in the final phase of peer review at RSC s Sustainable Energy and Fuels

Cobalt-containing molecular catalysts have become increasingly attractive for homogeneous photocatalytic H2 production in aqueous/organic/organic-aqueous solvents containing photosensitizers, proton donors, buffers, and sacrificial electron donors. This feat has attracted immense attention from both academic and industrial scientists and is connected to their unique characteristics and impressive catalytic performance alongside being cheap and earth-abundant. Mechanistic insights into H2 generation photocatalysis have been brought to the limelight by the triad of experimental, spectroscopic, and computational investigations leading to the seamless detection and identification of detailed understanding of real-time charge transfer dynamics and electronic and geometric structural variations within homogeneous systems. In this perspective, we give an overview of the competition between ligand tunability and photocatalytic condition optimization and the consequences of the competition on charge transfer dynamics between light-harvesting photosensitizers and catalytic species, variations in the geometric and electronic structures of catalytic species formed during photocatalysis, diversities of the reaction pathways, rate-limiting steps, and the stability, activity, and efficiencies of homogeneous H2 generation photocatalysis. The use of cobaloxime and others such as TiO2 as benchmarks for H2-evolving photocatalysts is fast becoming standard procedure and will be points of emphasis where necessary in the body of this work. It is projected that the dynamics of these photophysical and photochemical events will be utilized as guidance for future catalyst designs that will be competitive and compatible with existing global energy conversion technologies.
