Microemulsion method: A novel route to synthesize organic and inorganic nanomaterials

Synthesis of Nanocatalysts via Reverse Microemulsion Route for Fischer-Tropsch Reactions

“…The mechanisms by which nanoparticles are formed have been described by Malik and coworkers using two models (Malik et al, 2010). The first model is based on the Lamer diagram where nucleation occurs when the concentration of the precursor reactant reaches a critical supersaturation value, resulting in a constant number of nuclei thus size of particles increase with concentration (Malik et al, 2010).…”

“…The first model is based on the Lamer diagram where nucleation occurs when the concentration of the precursor reactant reaches a critical supersaturation value, resulting in a constant number of nuclei thus size of particles increase with concentration (Malik et al, 2010). In the second model, variation in the concentration of precursor does not change the size of particles as the particles are thermodynamically stabilized by the surfactant.…”

“…The core interior is hydrophilic thus certain water-soluble can be dissolved inside it. Microemulsion technique offers several advantageous for synthesizing nanoparticles as it enables controls of size, geometry and morphology (Malik et al, 2010).…”

“…A microemulsion is a liquid mixture of water, a hydrocarbon and a surfactant (Eriksson et al, 2004;Malik et al, 2010). A surfactant is a molecule that possesses both the polar (hydrophilic head) and the non-polar (hydrophobic tail) groups.…”

Micro Emulsion Synthesis of LaCoO3Nanoparticles and their Electrochemical Catalytic Activity

“…The properties of the final materials obtained are highly dependent on the preparation method [12][13][14][15][16]. The reverse micro emulsion, which is also known as W/O (water in oil) micro emulsion method, is a recently developed technique, ideal for the preparation of inorganic nanoparticles [17]. Water in oil micro emulsion proceeds by dispersing water phase (dispersion phase) in oil (continues phase).…”
