Abstract

Recently, considerable attention has been paid to the exfoliation of 2D inorganic layered materials as their physicochemical properties are significantly different from the bulk. However, the exfoliated 2D nanosheets readily undergo restacking and form a bulk-like structure due to van der Waals forces. Therefore, functionalization or decoration with foreign materials on the 2D nanosheets has been suggested to prevent the extent of restacking and tune their band gaps for emerging applications. Here, for the first time, we demonstrate the decoration of cube-shaped α-Fe2O3 nanoparticles on exfoliated h-BN nanosheets using a solvothermal method. Remarkably, the growth of the α-Fe2O3 particles was suppressed by the h-BN nanosheets, which resulted in the formation of a controlled size of the α-Fe2O3 nanoparticles over the exfoliated BN nanosheets. However, an increased lateral size was observed in the bare α-Fe2O3 nanoparticle synthesis. Then, the synergistic interaction between the α-Fe2O3 nanoparticles and the exfoliated BN nanosheets was identified by FT-IR analysis. XRD and Raman analysis further confirms the in situ formation of the phase pure α-Fe2O3 nanoparticles on the exfoliated BN nanosheets. The distribution of cube-shaped α-Fe2O3 nanoparticles over exfoliated BN nanosheets was characterized by SEM and HR-TEM analysis.
