“…In the case of MXene, the XPS spectrum of the Mo 3d component is displayed in Figure e at binding energies ∼227.2, 229.3, 230.4, and 233.7 eV, corresponding to Mo 2+ that emerges from Mo 2 C, Mo 4+ 3d 3/2 , Mo 6+ 3d 5/2 , and Mo 6+ 3d 3/2 , respectively. In Figure f, the XPS profile of C 1s consists of three deconvoluted peaks located at binding energies ∼280.2, 283.6, and 287.2 eV that are indexed to Mo 2 C, C–OH, and CO 3 2– , respectively. , Collectively, the acquired results of XPS analysis further validate the fabrication of the Mo 2 C@NiMn-LDH composite.…”
