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

Abstract

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.
