Accessing parity-forbidden d-d transitions for photocatalytic CO₂ reduction driven by infrared light.

ABSTRACT: A general approach to promote IR light-driven CO₂ reduction within ultrathin Cu-based hydrotalcite-like hydroxy salts is presented. Associated band structures and optical properties of the Cu-based materials are first predicted by theory. Subsequently, Cu₄(SO₄)(OH)₆ nanosheets were synthesized and are found to undergo cascaded electron transfer processes based on d-d orbital transitions under infrared light irradiation. The obtained samples exhibit excellent activity for IR light-driven CO₂ reduction, with a production rate of 21.95 and 4.11 μmol g^-1 h^-1 for CO and CH₄, respectively, surpassing most reported catalysts under the same reaction conditions.
