Left: Th L3 edge k3-weighted EXAFS spectra (dotted lines) and the best fits (solid lines) for the MXene samples under different solution pH. Right: corresponding non-phase-shift-corrected Fourier transforms. (a) Th(NO3)4·5H2O reference; (b) aqueous ThIV solution; (c) Ti3C2Tx-DMSO-H pH 2.0; (d) Ti3C2Tx-DMSO-H pH 3.0; (e) Ti3C2Tx-DMSO-H pH 3.4; (f) Ti3C2Tx-H pH 3.4. |
