(a) SEM image of the rhombus 2D-L-MOF particles obtained from the solvothermal reaction of Zn(NO3)2 (0.54 mmol) and H2BDC (1.62 mmol) in the presence of a stirring process. (b) SEM image of the rhombus 2D-L-MOF particles obtained from the solvothermal reaction of Zn(NO3)2 (0.54 mmol) and H2BDC (1.62 mmol) in the presence of an ultrasonic dispersion process (solvothermal ultrasonic reactions). (c) SEM image of the rhombus 2D-L-MOF particles obtained from the solvothermal ultrasonic reaction of Zn(NO3)2 (0.54 mmol) and H2BDC (1.62 mmol); however, an ultrasonic dispersion process was stopped immediately after the initial seed formation. (d)–(f) PXRD patterns of the rhombus 2D-L-MOF particles shown in (a)–(c), respectively.
