Pd–Co–Au/C catalysts synthesized by the conventional borohydride reduction method and reverse microemulsion method followed by heat treatment at 500–900 C in a reducing atmosphere have been characterized by X-ray diffraction, transmission electron microscopy, and polarization measurements for oxygen reduction reaction (ORR) in proton exchange membrane fuels cells. While a single phase Pd–Co–Au ...

Microemulsion science has provided a wide range of possibilities in materials fabrication. Here, we describe a novel approach to the synthesis of SrTiO3 nanoparticles of different shapes from a microemulsion. We show that the microemulsion structure plays a critical role in the shape of the nanoparticles, with diffusion-limited growth when normal or reverse micelles are present to nanocuboids w...

In this work needle like hydroxy apatite were synthesized in a reverse microemulsion droplets of water in cyclohexane, separated by a cationic surfactant and co-surfactant, in the presence of Na-polyacrylate (PAA) as an anionic polyelectrolyte. Characterization of the as formed HAp nanoparticles at the room temperature were carried out by X-ray diffraction (XRD) and Fourier transform infrared s...

Hydrophobic layered double hydroxide particles with a single layer structure have been successfully synthesised in a reverse microemulsion system; atomic force microscopy has proven a powerful tool for the study of these delicate nanoparticles.

Mesoporous polymer materials were fabricated from micelle/polymer precursors prepared by the micelle template method in reverse microemulsion systems and the pore size could be tuned by varying the type and concentration of surfactant.

Antimosy-doped tin oxide (ATO) particles were prepared via chemical coprecipitation and reverse emulsion. The size and size distribution of ATO particles were obviously decreased via reverse microemulsion method. At the relatively high yield the ATO particles were nearly spherical in shape, meanwhile the crystalline structure and excellent conductivity were reserved, which could satisfy the req...
