Synthetic illustration of a M-Ti3C2Tx, and b U-Ti3C2Tx MXenes. Comparison of component peak-fitting of XPS spectra for M-Ti3C2Tx, and U-Ti3C2Tx Ti2p at c TiO2 2p3/2, and d TiO2 2p1/2. e Composition of the Ti3C2Tx surface functional groups produced by etching of the Ti3AlC2 in HF and LiF–HCl solutions, per Ti3C2 formula unit, i.e., Ti3C2(OH)xFyOz. f XRD patterns of Ti3AlC2 and Ti3C2Tx etched with HF or LiF–HCl.
