Pulsed‐Laser‐Driven CO₂ Reduction Reaction for the Control of the Photoluminescence Quantum Yield of Organometallic Gold Nanocomposites

CO2 Reduction Reaction In article number 2300328, Anna Laurenzana, Tommaso Del Rosso, and co-workers show the fixation of CO2 into solid nanomaterials in the colloidal phase by laser synthesis and processing of gold colloids in water, traditionally considered a green approach leading to ligand-free nanoparticles without the formation of by-products. The pulsed laser driven CO2 reduction reaction leads to the formation of carbon monoxide rich gold nanoparticles and organometallic nanocomposites composed by gold nanoclusters and carboxylic acid salts, characterized by a photoluminescent quantum yield of about 20% in the visible (blue) region.
