Nanoparticles encompass great potential in the current era due to their small
size. They are employed in a myriad of applications, from biotechnology to
manufacturing and energy applications. The production of nanoparticles, therefore, has
been a focus of interest for researchers since its inception. Amongst non-conventional
methods for nanoparticle production, Spark Discharge has emerged as an effective and
viable method. This review encapsulates various experiments and works done over the
years on the application of the spark discharge method for the production of
nanoparticles and postulates the prospects of future work in the field. Different ways to
control nanoparticle size by altering different parameters such as dielectric medium
spark frequency, the gap between electrodes, and energy per spark and flow rate have
been explored. Contrast has been drawn between conventional and non-conventional
processes of nanoparticle production. In conclusion, new non-conventional techniques
and hybrid techniques for nanoparticle production with spark discharge methods have
been discussed, along with the applications of nanoparticles in emission control,
cooling and lubrication.
