Earth-abundant-metal complexes as photosensitizers in molecular systems for light-driven CO2 reduction

Unveiling the Activity and Mechanism Alterations by Pyrene Decoration on a Co(II) Macrocyclic Catalyst for CO2 Reduction

“…CO 2 reduction has been viewed as a versatile reaction for both relieving the global warming and providing carbon-neutral, renewable fuels. [1][2][3] Molecular catalysis utilizing transition metal complexes is promising to address efficiency and selectivity issues in CO 2 reduction; their well-defined structures facilitate the optimization of their catalytic performances by means of identification of catalytic intermediates and determination of their operative mechanisms. [4][5] The molecular catalysts based on earth-abundant metals are relatively appealing for their merits in lowering the expense for large-scale applications.…”

Directed Electron Delivery from a Pb‐Free Halide Perovskite to a Co(II) Molecular Catalyst Boosts CO2 Photoreduction Coupled with Water Oxidation

“…However, the involvement of multiple electron/proton transfer processes in CO 2 reduction and the diverse product distribution along with competitive H 2 evolution both demand the rational design of efficient and selective photocatalytic systems [3] . It will be more attractive to fabricate the catalytic systems with only earth‐abundant elements in order to avoid the high expense and scarcity from noble‐based metals [4–5] . Semiconducting metal halide perovskite (MHP) continues to attract attention in constructing high‐performance photocatalytic systems for CO 2 reduction with their earth‐abundant nature and broad visible‐light absorption [6–12] .…”

Visible-Light-Driven Carbon Dioxide Reduction Catalyzed by Iron Schiff-Base Complexes

“…The energy needed for driving the reaction can be provided by low-carbon electricity or directly by solar power and the reaction kinetics can be greatly improved by molecular or solid catalysts. Specifically, light-induced reduction of CO 2 using a sacrificial electron donor, providing a strong driving force, is a practical way for studying and evaluating the potential of molecular complexes as catalysts of CO 2 conversion. − It furthermore represents the reductive half-reaction of an artificial photosynthetic device, e.g., photoelectrochemical cell, to be coupled to the oxidative half-reaction, preferentially the energy demanding water oxidation to oxygen. Under standard conditions, the reaction takes place in a solution, most often an organic solvent and more rarely pure water, containing the catalyst, a proton source, a sacrificial reducing agent, and a photosensitizer (PS).…”
