Special Issue Information

Dear Colleagues,

Metal oxide nanoparticles nowadays represent an intense field of research due to the myriad of applications envisaged. The well-stablish technological interest of metal oxides and the unusual properties of a nanomaterial are combined in this exciting field that is continuously generating advances in catalysis, sensing, optoelectronics, actuators, etc.

We invite researchers to contribute for this special issue “Synthesis, Properties and Applications of Metal Oxides Nanoparticles” with original advances on the following topics:

  • Novel and eco-friendly synthetic approaches to control nanoparticle microstructure
  • Post synthetic treatments of metal oxide nanoparticles:  functionalization, stabilization, dispersion or processing as thin film
  • Fundamentals on relationships between structure/function of metal oxide nanoparticles
  • Distinctive and superior functional properties (optical, magnetic, catalytic, electronic, etc.) of metal oxide nanoparticles
  • Applications of metal oxide nanoparticles in different fields (biomedical, optics, electronics, sensing, catalysis, etc.) linked to their functional properties

This Special Issue intends be a gathering of researchers that make their efforts in those topics to promote recent advances in this field.

Ferroelectric materials are crucial for today’s technological society and nanostructured ferroelectric materials are important for the downscaling of devices. Controlled and reproducible synthesis of these materials are, therefore, of immense importance. Hydrothermal synthesis is a well-established synthesis route, with a large parameter space for optimization, but a better understanding of nucleation and growth mechanisms is needed for full utilization and control. Here we use in situ X-ray diffraction to follow the nucleation and growth of BaTiO3 formed by hydrothermal synthesis using two different titanium precursors, an amorphous titania precipitate slurry and a Ti-citric acid complex solution. Sequential Rietveld refinement was used to extract the time dependency of lattice parameters, crystallite size, strain, and atomic displacement parameters. Phase pure BaTiO3 nanoparticles, 10–15 nm in size, were successfully synthesized at different temperatures (100, 125, and 150 °C) from both precursors after reaction times, ranging from a few seconds to several hours. The two precursors resulted in phase pure BaTiO3 with similar final crystallite size. Finally, two different growth mechanisms were revealed, where the effect of surfactants present during hydrothermal synthesis is discussed as one of the key parameters. Full article
