MXene,very recently emerging family of two-dimensional (2D) transition metal carbides and/or nitrides,have attracted a wide range of attention due to unique layered structure,hydrophilicity,high conductivity and catalytic activity.First,synthesis and various applications of MXene in adsorption,photocatalysis and membrane separation were summarized in this review.Then,the effects of structure control,surface modification and composite of MXene on the adsorption performance of MXene and the formation of effective heterojunction,the exposure of active crystal face and the deposition of precious metals on the catalytic performance of MXene based photocatalysts were discussed.The approaches of constructing MXene based separation membrane for separating pollutants and desalinating seawater were described in detail.Finally,the existing problems in the applications of MXene in the field of water treatment were summarized and analyzed,and the prospects of designing MXene based water treatment materials with excellent performance were put forward.
