Synthesis of Functional Nanostructures by Sustainable Solution Chemistry

About this Research Topic

Nanotechnologies based on abundant and air-stable materials in combination with cost-effective fabrication techniques can drastically reduce the demand of scarce elements giving rise to innovative and sustainable social solutions, ranging from energy to health applications. In this light, the miniaturization of devices by using nanostructures performs in two-fold: it can induce enhanced properties and, perhaps more importantly, can save costs in resources, granting more efficient economic policies. The versatility offered by chemical solution deposition (CSD) allows us to obtain a huge palette of nanostructures like coatings, thin films, multilayers, nanoparticles, nanorods, nanowires, composites, etc. of different families of both simple and complex oxides (perovskites, garnets, spinels, etc.) and other materials such as chalcogenides or pnictides. In particular, functional oxides provide a large variety of physical properties which can be tuned at the nanoscale through their stoichiometry, oxygen vacancies, crystallinity, or strain. The obtention of advanced applications of nanomaterials by means of aqueous CSD methods represents a huge step forward in this research area, which simultaneously fits in line with the environmental concerns of today.


The objective of this Research Topic is to showcase the current research on functional nanostructures obtained by sustainable CSD routes, presenting state-of-the-art methodology and applications. A special emphasis is given to the relevant chemical aspects such as ligands, hydrosoluble polymers, metal sources in the precursor solutions and to the crystallization process, promoted by heating or light to achieve crystalline nanomaterials. The distinctive growth regime of the chemical methods offers a genuine pathway to stabilize elusive phases and exotic morphologies of the nanomaterials. Moreover, CSD methods can be not only an affordable alternative to physical technologies but also a joint route with physical methods to prevent some limitations of a single technique adding extra functionalities.


This Research Topic involves the synthesis and applications of nanostructures of functional nanomaterials (oxides, chalcogenides, pnictides, oxypnictides, etc.) by using chemical sustainable methods, with particular attention to aqueous-based methods. The interests of this Research Topic include:

·      Synthesis and characterization of nanostructures.

·      Chemically driven phase stabilization in nanomaterials.

·      Devices based on functional oxides, chalcogenides, pnictides and oxypnictides.

·      Interfacial and low-dimensional properties.

·      Nano-engineering of nanomaterials with CSD methods.

·      Comparison of chemical methods to physical methods.

·      Combination of chemical and physical methods.


Keywords: nanomaterials, chemical solution synthesis, functional oxides, epitaxial interfaces, sustainable methods
