Implication

Experimental study reveals potassium intercalation enhances structural homogeneity and restricts water diffusion in MXenes, indicating superior stability against environmental fluctuations.

Key Points

Investigate how intercalating metal ions influences the internal structural ordering and water dynamics of hydrophilic 2D MXenes under ambient conditions.
Characterized structural organization and interlayer water dynamics in MXenes using complementary X-ray and neutron scattering techniques.
Performed molecular dynamics simulations to evaluate water mobility and behavior in the presence of intercalated potassium cations.
Intercalation with potassium cations markedly improved structural homogeneity and water stability within the MXene layers.
Potassium ions decreased the water self-diffusion coefficient by two orders of magnitude compared to non-intercalated hydrated MXene.
