What is the better method to determinated the mephology of nanoparticles.
@ Laouini, most widely used technique for nanoparticle morphology characterization is the use of Scanning electron microscope (SEM). The signals that derive from electron-sample interactions reveal information about the sample including surface morphology (texture), chemical composition of the sample. The other instrument you can use are :Transmission electron microscope, Atomic force microscopy, Ray diffraction, Thermal analysis and Nuclear magnetic resonance.

Morphology is the science of the structure and shape of nanoparticles.
The structure can be studied by XRD, SEM, TEM, IR, visible spectroscopy, NMR, EPR, circular dichroism spectroscopy, SERS, DLS, magnetometry
The shape can be studied by SAXS, TEM, SEM, cryogenic TEM, small angle neutron scattering, AFM
Scanning electron microscope
SEM forvsurface morphology
Transmission electron microscope for bulk.

To determine the morphology of the nanoparticles, SEM, FE-SEM, or TEM are well-known techniques. All the best with your research !!
HR-SEM is used to study the morphology of bulk materials, but HR-TEM is used to study the morphology of nano-particles.
