Description:
Tantalum(V) oxide (Ta2O5) nanospheres have been synthesized by a very simple ethylene glycol mediated route. The two-step process involves the formation of glycolate nanoparticles and their subsequent hydrolysis and calcination to generate the final Ta2O5 nanospheres. The synthesized particles are characterized by XRD, TEM and SEM. The particles sizes could be tailored from 50 nm to 500 nm or more by changing the reaction conditions. The final particles are highly dispersed under appropriate reaction conditions. The process does not require any specific equipment or high vacuum technique for the production of the nanoparticles.
