Abstract
Abstract A general approach to promote IR light-driven CO 2 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, Cu 4 (SO 4 )(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 CO 2 reduction, with a production rate of 21.95 and 4.11 μmol g −1 h −1 for CO and CH 4 , respectively, surpassing most reported catalysts under the same reaction conditions. X-ray absorption spectroscopy and…
