Efficient Visible-Light-Driven Carbon Dioxide Reduction using a Bioinspired Nickel Molecular Catalyst

Abstract[edit | edit source]

The study introduces a bioinspired nickel-based molecular catalyst, [Ni(N2S2)]Cl2 (NiN2S2), for photochemical catalytic reduction of CO2 under visible light. Combining the catalyst with [Ru(bpy)3]Cl2 as a photosensitizer and BIH as a sacrificial electron donor, the system achieved an 89% selectivity towards CO, with a turnover number (TON) of 7991 during 8 hours of irradiation. The process demonstrated high catalytic efficiency with a turnover frequency (TOF) of 1079 h⁻¹ and an apparent quantum yield (AQY) of 1.08%.
