Abstract

Abstract To address the environmental crisis caused by excessive emissions of CO2, the development of effective photocatalysts for the conversion of CO2into chemicals has emerged as one of the most promising strategies. Herein, beyond those well‐studied materials, a rare‐earth sulfide‐based nanocrystal NaCeS2is fabricated and investigated for efficient and selective conversion of CO2into CO, where the role of Ce ions is crucial. Firstly, the hybridization of Ce 4f and Ce 5d orbitals contributes to the photoresponsive band structure of NaCeS2. Secondly, due to the charge rearrangement supplied by the incompletely filled 4f orbitals of Ce ions, NaCeS2exhibits excellent charge separation efficiency and CO2adsorption affinity, reducing the energy barrier for the conversion from CO2to CO. Moreover, a NaCeS2‐MoS2heterostructure is also designed to further boost the electron transfer from the Mo site to the Ce site, which results in an improvement of the catalytic reduction yield from 7.24 to 23.42 µmol g−1within 9 h (both better than TiO2controls). This work offers a platform for the development of rare‐earth‐based photocatalysts for CO2conversion.
