Synthesis and Structural Characterization of Ti₂C Nanosheets

In this paper, two-dimensional (2D) Ti2C nanosheets were synthesized by exfoliation of Ti2AlC powders in HF solution at room temperature. The surface atomic composition and chemistry of as-prepared Ti2C nanosheets were studied by XPS. The specific surface area of Ti2C nanosheets were determined by BET. The as-prepared Ti2C nanosheets are stacked and held together, which leads to the lower specific surface area of the as-prepared Ti2C nanosheets.
