Preparation and Electrochemical Property of Monolayer Ti3C2Tx Nanosheets with Different Lateral Dimension

Recently, a new type of 2D transition metal carbides or nitrides (MXene) has attracted wide attention due to its large specific surface area, good hydrophilicity, metallic conductivity and other physical and chemical properties. 2D Ti 3 C 2 T x MXene was obtained by etching Al layer of Ti 3 AlC 2 with LiF and HCl and then mechanically delaminated. And the monolayer Ti 3 C 2 T x nanosheets with lateral dimension of 625 and 2562 nm can be prepared by changing the intensity and way of mechanically delamination, as well as the centrifugation rate and time.
