Layer-dependent properties of nanoconfined water (IMAGE)
Caption
(a) The atomic resolution HAADF images of three distinct phases with interlayer spacing of 1.29, 1.45 and 1.57 nm, respectively. (b) the local snapshot of Mn-MXene-N model with 3-layer (15.8 Å), 2-layer (14.4 Å) and 1-layer (13.0 Å) water in-between layer of MD simulation, with the probability density profiles of water molecules along the c lattice direction displayed on the left side. (c) The trends of the initial phase residue and capacitance enhancement of Mn-MXene-N during CV pre-cycles. (d) Low field 1H time-domain nuclear magnetic resonance spectra of the indicated samples. The shaded region represents the time-domain region of interlayer water.
