Tera-hertz (THz) catalysis on MXene for enhanced selectivity from CO2 to CO

Applying Natural Language Processing (NLP) to journals about catalytic reaction, we found a gap between photocatalysts and thermal catalysts, where Tera-Hertz (THz) catalysis is located; therefore, we have investigated THz catalysis in this work. We report an excellent Ti3C2F2 MXene electrocatalyst that can accelerate the catalytic process of the hydrogen evolution reaction (HER) and carbon dioxide reduction reaction (CO2RR). In the CO2RR reaction, high selectivity toward the gaseous product CO is observed. The THz catalysis is achieved through the resonance between the vibrational mode of CO2 and the surface phonon mode. Detailed computational studies are discussed. Potential applications of MXene in THz catalysis in the future are also expected.
