Recently a large family of two-dimensional (2D) layered early transition metal carbides and carbonitrides – labelled MXene – possessing metallic conductivity and hydrophilic surfaces was discovered. Herein we report on the adsorption and photocatalytic decomposition of organic molecules in aqueous environments containing Ti3C2Tx, a representative of the MXene family. This material possesses excellent adsorption toward cationic dyes, best described by a Freundlich isotherm. We also found that…

Graphite oxide (GO) was prepared by a modified Hummers−Offeman method and was tested as an adsorbent for the removal of dyes in aqueous solution. The structure of GO was characterized by N2

Oxygen adsorption and dissociation during the oxidation of monolayer Ti2C

Exfoliated two-dimensional early transition metal carbides and carbonitrides are usually not terminated by metal atoms but saturated by O, OH, and/or F, thus making it difficult to understand the
