Sulfur Doped Ti 3 C 2 T x MXene Anchored Zinc for Efficient Electrocatalytic CO 2 Conversion to CO
Year: 2025
Type: article
Abstract: To investigate the potential of MXene‐catalyzed electroreduction of carbon dioxide towards achieving highly efficient ECO 2 RR, this study engineered an S ‐anchoring site on Ti 3 C 2 T x MXene for Zn ion coordination. The findings revealed that S was uniformly distributed across the MXene surface and interface, either replacing or integrating with functional groups, and effectively coordinating with Zn. Subsequently, Zn nanoparticles were synthesized leveraging the defect‐induced self‐reduction capability of the MXene support. The presence of MXene facilitated rapid electron transfer to Zn, accelerated the activation of carbon dioxide, and endowed Zn‐S‐MXene with a larger active surface area, enhanced ECO 2 RR selectivity, and a faster charge transfer rate. Consequently, the CO selectivity was significantly enhanced, reaching an impressive FE of 89.7%. This study offers novel perspectives on the utilization of atomic modifications in MXene materials for the design and optimization of ECO 2 RR through the strategic pairing with metal ions.
