“…As summarized in Table 1, a number of publications have been made on the enhancement of specific heat of molten salts using nanoparticles [2,3,4,5,6,7,8,13,14,15,16,17,18,19,20,21,22,23]. However, most publications (Table 1—First 16 Rows) follow the same methodology of production with very little deviation [21,22].…”

Seeding nanoparticles in molten salts has been shown recently as a promising way to improve their thermo-physical properties. The prospect of such technology is of interest to both academic and industrial sectors in order to enhance the specific heat capacity of molten salt. The latter is used in concentrated solar power plants as both heat transfer fluid and sensible storage. This work explores the feasibility of producing and dispersing nanoparticles with a novel one pot synthesis method. Using such a method, CuO nanoparticles were produced in situ via the decomposition of copper sulphate pentahydrate in a KNO3-NaNO3 binary salt. Analyses of the results suggested preferential disposition of atoms around produced nanoparticles in the molten salt. Thermal characterization of the produced nano-salt suspension indicated the dependence of the specific heat enhancement on particle morphology and distribution within the salts.

“…They proved that application of MWCNT and Au nanoparticles to the binary molten salts can remarkably increase the specific heat capacity by a factor approaching 100%. However, In a research study conducted by Chierruzi et al, [18], they reported reduction of 16.4% in cp value for solar salt induced with 0.5 wt.% of SiO2 nanoparticles in solid phase as well as 19.3% decrease in cp value in liquid phase. They proved the reduction of 14.4% and 15.6% in cp value for solar salt mixture with TiO2 nanoparticles in the solid and liquid phases, respecticely.…”
