- Abstract
Owing to the inertness of CO
2 molecules, the development of highly active photocatalysts for CO2 reduction reactions (CO2 RR) remains a formidable challenge. Here, we designed an MXene-based single-atom Fe co-catalyst (Fe1 /Ti3−x C2 Ty ) featuring fast Ti–Fe electron channels to achieve enhanced CO2 RR performance. The synthesized Fe1 /Ti3−x C2 Ty exhibited a CO yield of 259.0 μmol g−1 h−1 without the addition of any organic sacrificial agents. The experimental and computational results reveal that, electrons transfer from Ti to Fe and then accumulate at the active sites, which facilitates the transfer of charges and enhances the activation of CO2 molecules. This work provides a new direction of MXene-based non-noble-metal monoatomic catalysts for efficient photoreduction of CO2 under gas–solid photocatalytic conditions with pure water.
