Structure of nanocrystalline Ti3C2 MXene using atomic pair distribution function.
نویسندگان
چکیده
The structures of nanocrystalline pristine, potassium hydroxide and sodium acetate intercalated new two-dimensional materials Ti3C2 MXenes were studied using the x-ray atomic pair distribution function technique. Pristine MXene has a hexagonal structure with a=b=3.0505(5) Å, c=19.86(2) Å (S.G. P63/mmc No. 194). Both hydroxyl and fluoride terminating species are present. The intercalation of K+ or Na+ ions expands the Ti3C2 layers perpendicular to the planes but shrinks the in-plane a and b lattice parameters.

Ti3C2 MXene co-catalyst on metal sulfide photo-absorbers for enhanced visible-light photocatalytic hydrogen production
Scalable and sustainable solar hydrogen production through photocatalytic water splitting requires highly active and stable earth-abundant co-catalysts to replace expensive and rare platinum. Here we employ density functional theory calculations to direct atomic-level exploration, design and fabrication of a MXene material, Ti3C2 nanoparticles, as a highly efficient co-catalyst. Ti3C2 nanoparti...
متن کاملAtomically Resolved Structural and Chemical Investigation of Single MXene Sheets.
The properties of two-dimensional (2D) materials depend strongly on the chemical and electrochemical activity of their surfaces. MXene, one of the most recent additions to 2D materials, shows great promise as an energy storage material. In the present investigation, the chemical and structural properties of individual Ti3C2 MXene sheets with associated surface groups are investigated at the ato...
متن کاملOn the organization and thermal behavior of functional groups on Ti3C2 MXene surfaces in vacuum
The two-dimensional (2D) MXene Ti3C2Tx is functionalized by surface groups (Tx) that determine its surface properties for, e.g. electrochemical applications. The coordination and thermal properties of these surface groups has, to date, not been investigated at the atomic level, despite strong variations in the MXene properties that are predicted from different coordinations and from the identit...
متن کاملAtomic-scale structure of nanocrystalline CeO2–ZrO2 oxides by total x-ray diffraction and pair distribution function analysis
Total x-ray diffraction and atomic pair distribution function analysis have been used to determine the atomic ordering in nanocrystalline (∼1.5 nm in size) CeO2–ZrO2 prepared by a sol–gel route. Experimental data show that the oxides are a structurally and chemically inhomogeneous mixture of nanoscale domains with cubic-type and monoclinic-type atomic ordering, predominantly occupied by Ce and ...
متن کاملStructure of Nanocrystalline Materials by the Atomic Pair Distribution Function Technique
The approach of the atomic pair distribution function (PDF) technique to study the structure of nanocrystalline materials is considered and successfully applied to V2O5.nH2O xerogel and Cs intercalated inside the pores of the zeolite ITQ-4. We find that V2O5.nH2O is an assembly of almost perfect bi-layers of VO5 units encapsulating the water molecules. Inside the nanopores of ITQ-4 the cesium i...
