Two-dimensional graphene Oxide/MXene composite lamellar membranes for efficient solvent permeation and molecular separation

Ultra-lightweight Ti3C2T MXene modified separator for Li–S batteries: Thickness regulation enabled polysulfide inhibition and lithium ion transportation

“…The X-ray diffraction (XRD) patterns of the Ti 3 AlC 2 powder and a modified separator are shown in Fig. 3 Ti 3 C 2 T x was produced [36] . X-ray photoelectron spectroscopy (XPS) was performed to identify the chemical components and their valences on the Ti 3 C 2 T x -PP separator surface [36,37] .…”

“…3 Ti 3 C 2 T x was produced [36] . X-ray photoelectron spectroscopy (XPS) was performed to identify the chemical components and their valences on the Ti 3 C 2 T x -PP separator surface [36,37] . An XPS survey spectrum of the Ti 3 C 2 T x -PP separator is shown in Fig.…”

“…The peaks in the O 1 s spectrum centered at 532.98, 531.88, and 530.48 eV were assigned to oxygen in C -OH, Ti -OH, and Ti -O -Ti bonds, respectively. The O 1 s peak at 529.48 eV was attributed to oxygen adsorbed to the surface [36] . Due to the various chemical components on the Ti 3 C 2 T x surface, chemical interactions effectively suppressed LPS shuttling [30] .…”

MXene Materials for Designing Advanced Separation Membranes

“…[132] Copyright 2019, Elsevier B.V. the organic dye molecules larger than >2.0 nm from isopropanol ( Figure 8d). [109] More recently, Wei et al [130] reported a nylon-supported GO/MXene hybrid NLM that can also reach over 90% dye rejection rates (Figure 8e). While testing their membranes with different organic solvents (i.e., acetone, methanol, ethanol, and isopropanol), they also demonstrated the high stability of hybrid MXene-GO NLMs for long-term operations.…”
