Chemical exfoliation of layered Al₅C₃N for the synthesis of AlN nanosheets.

ABSTRACT: Two-dimensional (2D) aluminum nitride (AlN) represents a promising material with unique properties predicted by density functional theory (DFT), characterized by a honeycomb lattice where Al and N atoms exhibit threefold in-plane coordination. However, the synthesis of free-standing AlN nanosheets has been challenging due to the crystal configurations of the well-known bulk AlN, which presents a hexagonal wurtzite structure with a tetrahedral coordination, preventing its exfoliation to obtain nanosheets. Herein, we propose a facile method involving the preparation of layered-structured aluminum carbonitrides, Al₅C₃N, followed by exfoliation into AlN nanosheets, offering a potential route for producing 2D AlN. The Al₅C₃N precursor was chemically e
