Photocatalytic Activity of the Oxidation Stabilized Ti3C2Tx MXene in Decomposing Methylene Blue, Bromocresol Green and Commercial Textile Dye

“…[12,15,16] MXenes are a large family of 2D early transition metal carbides and/or nitrides, described for the first time in 2011 by Naguib et al [17] MXenes are synthesized from their parental MAX phases-layered ternary compounds, with the M n+1 AX n formula in which "M" is an early transition metal, "A" refers to elements from groups 13 and 14 in the periodic table, "X" is carbon and/or nitrogen, and n = 1, 2, 3 or 4. [18][19][20][21] MXenes have the general formula of M n+1 X n T x in which T x represents surface functional groups, mostly −O, −OH, −F, and −Cl. [22] MXenes also show a direct-to-indirect band gap switching upon the surface termination, thus combining the optical properties with hydrophilic nature [23,24] and a large specific surface area.…”
