Spherical particles of one or more elemental metals and elemental carbon are prepared from a precursor in the form of a metal oleate. The metal oleate precursor is dispersed in a liquid vehicle and aerosol droplets of the dispersed precursor are formed in a stream of an inert gas. The aerosol droplets are heated in the stream to decompose the oleate ligand portion of the precursor and form spherical particles that have a mesoporous nanocrystalline structure. The open mesopores of the spherical particles provide a high surface area for contact with fluids in many applications. For example, the mesopores can be infiltrated with a hydrogen absorbing material, such as magnesium hydride, in order to increase the hydrogen storage capacity of the particles.

The various embodiments herein provide a system and method for enhancing polymerization and nanoparticles production using a disc reactor. The system comprises a rotating disc comprising a first surface and a second surface arranged longitudinally along a single axis of rotation, a shaft attached to the rotating disc, a ring provided on top of the first surface of the rotating disc, at least one feed inlet for providing a feed solution, a fluid inlet for providing a heat transfer fluid, a fluid outlet for exiting the heat transfer fluid, a product collector for collecting the produced nanoparticles and a product outlet for exiting the produced nanoparticles. The feed solution flows from the first surface to the second surface of the rotating disc due to centrifugal forces and gets accumulated on the product collector and exits from the disc reactor through the product outlet.
