2D hexagonal boron nitride, graphene, molybdenum disulphide and tungsten disulfide nanosheets were successfully prepared at mild temperature using a facile “recrystallization of NaCl” exfoliation method. The proposed method was simple, inexpensive and practical. The thicknesses of the h‐BN, graphene, MoS 2 and WS 2 nanosheets were approximately 1.5, 1.1, 1.2 and 1 nm, respectively. It was very interesting that the 2D nanosheets exhibited excellent thermal catalytic degradation performance during preparation of carbon quantum dots by using ethylene glycol. What's more, nitrobenzene (NB) was also degraded and the best degradation rate of NB was 71% at 6 h in the thermal catalytic system. This interesting discovery will lead to new research directions for two‐dimensional materials.
