Ultrasound exfoliation. SEM images of as-synthesized 2D Ca-MOF bulk crystals (a), and the obtained nanobelts after ultrasound exfoliation in H2O (b). AFM images (c) and the corresponding height profile (d) of two randomly selected nanobelts. SEM images of the obtained nanosheets (NS-1) (e) and nanospheres (f). AFM image (g) and height profile (h) of NS-1. PXRD patterns (i) and emission spectra (j, shown in peak-deconvolution manner by dash lines, λex = 408 nm) of Ca-MOF bulk crystals, nanobelts, nanospheres and NS-1 samples
