Implication

Experimental study demonstrates selective carbon dioxide adsorption in two-dimensional Ti3C2 MXenes, highlighting their viability as stable solid sorbents for carbon capture.

Key Points

Evaluate the carbon dioxide adsorption capacity, gas selectivity, and stability of two-dimensional transition metal carbide (MXene) nanosheets for carbon capture applications.
Measured carbon dioxide (CO2) and nitrogen (N2) gas adsorption profiles on individual sheets of Ti3C2 MXene.
Conducted first-principles calculations to model gas interactions and assess theoretical selectivity.
Individual Ti3C2 MXene sheets exhibited an effective CO2 adsorption capacity of approximately 12 mol kg^-1.
Exposure to N2 gas resulted in no measurable adsorption, confirming high CO2/N2 selectivity alongside chemical and thermal stability.
