A Review on Synthesis and Characterisation of Nanoclusters

Dr Esther Leena Preethi, Petricia Sara Peter

Abstract


Nanoclusters are materials with size less than 2 nm. Because of their small size and high surface area, they have properties which can be used for various applications like bio-sensing, catalysis, fuel cells etc. The synthesis techniques are carried out in such a way that the size-selection of nanoclusters take place. The synthesis methods discussed in this review include both top-down and bottom-up techniques. The different characterization techniques taken into consideration are X-ray diffraction (XRD), transmission electron microscope (TEM), scanning electron microscope (SEM), atomic force microscope (AFM), vibrating sample magnetometer (VSM) and UV-Visible spectroscopy. The distinct properties of nanoclusters were exemplified and confirmed.
