摘要：

The layered Ti3C2 was successfully fabricated by etching the Al layer of Ti3AlC2 with the assistance of trifluoroacetic acid (TFA). By controlling the reaction time, the residual Ti3AlC2 phase in the Ti3C2 materials can be well removed by the TFA and the thickness of single Ti3C2 layer is similar to 10 nm. The absorption activity of the samples were also evaluated by adsorbing Congo red (CR) in the aqueous solution. The layered Ti3C2 exhibits much better absorption performance than that of pristine Ti3AlC2 and the maximum adsorption amount of CR is up to 351 mg g(-1). This work develops a novel strategy to synthesize layered Ti3C2 without using the corrosive solvent.
