Electronic structure modulation via single atom interfacial engineering for selective atmospheric CO2 photoreduction

Abstract

Single-atom iridium was interfacially engineered on CuFeS₂ quantum dots (QDs) with highly efficient CO₂ photoreduction performance. The electronic structure modulation yielded a remarkable CO yield rate of 32.5 μmol g⁻¹ h⁻¹ with 92.2% selectivity under atmospheric conditions. This work demonstrates the potential of single-atom interfacial engineering for advancing CO₂ photoreduction.
