A wide range of inorganic nanomaterials with many fascinating properties and application potentials in widespread fields may be synthesized by wet chemical synthetic routes. To achieve scientific and commercial viability of nanomaterials with uniformity and scalability, it is necessary to develop efficient and cost-effective, preferably sustainable, methods. The molten salt synthesis (MSS) method is one such bottom-up technique to fabricate a wide variety of inorganic nanomaterials with tunable size, morphology, and surface characteristics. It is also environmentally friendly, cost-effective, simple to operate, easy to scale, and generalizable, etc. This review gives a critical overview on this emerging and rapidly developing method for making defect free nanomaterials in well-defined texture, surface, and morphology at a relatively low formation temperature. We have discussed its different aspects, including the role of molten salts, the choice of molten salts, the electrochemical aspects, some advanced modifications of the conventional MSS technique, and their implications. To show the most recent development on MSS synthesized inorganic nanomaterials, this review only encompasses the studies reported over the last six years (2015−2020). We have summarized technologically important and emerging families of inorganic nanomaterials such as metal oxides, fluorides, nitrides, silicides, chalcogenides, oxohalides, borides, and carbides. Finally, a few perspectives for the MSS method are highlighted. It is expected that this review will further attract scientists to explore the MSS method in making size-and shape-tunable nanomaterials.

“…The solubilities of metal oxides in molten fluxes have been previously studied using thermodynamic and potentiometric determination methods. [43][44][45][46][47][48][49][50][51][52] The use of fluxes with the same cations as the desired metal-oxide typically yields phase-pure crystals as a result of the similar chemical bonding, coordination site preference electronegativity, and crystal radii. As a general guideline, the hard-soft acid-base (HSAB) theory can be used to predict the solubility of inorganic reactants in molten-salt fluxes.…”

Flux-mediated crystal growth of metal oxides: synthetic tunability of particle morphologies, sizes, and surface features for photocatalysis research

Molten-salt reactions can be used to prepare single-crystal metal-oxide particles with morphologies and sizes that can be varied from the nanoscale to the microscale, subsequently enabling a growing number of novel investigations into their photocatalytic activities. Crystal growth using flux-mediated methods facilitates finer synthetic manipulation over particle characteristics. The synthetic flexibility that flux synthesis affords for the growth of metaloxides has led to the stabilization of phases limited stability, the discovery of new compositions, and access to alternate crystal morphologies and sizes that exhibit significant changes in photocatalytic activities at their surfaces, such as for the reduction of water to hydrogen in aqueous solutions. This approach has significantly impacted the current understanding of the optical and photocatalytic properties of metal-oxides, such as the dependence of band gap energies on the structure and chemical composition (i.e., obtained from flux-mediated ionexchange reactions). Thus, flux preparations of metal-oxide photocatalysts assist in the growth 2 and optimization of their particles in order to understand and tune the photocatalytic reaction rates at their surfaces.
