High-efficiency and simple synthesis of Ti 3 C 2 T x nanoscrolls by surface energy modulation and cryogenic freezing.

To alleviate the restacking issue of 2D Ti 3 C 2 T x itself, we purposefully explore a simple but efficient method for controllable construction of 1D Ti 3 C 2 T x nanoscrolls with a high efficiency of ∼90.5%, with detailed regulation of the feed concentrations and surface energy of Ti 3 C 2 T x . The involved transformation mechanism from 2D nanosheets to 1D nanoscrolls is reasonably proposed.
