Special Issue Information

Dear Colleagues,

Nanosized materials have attracted considerable interest because of their unique structure and functionality that could be applicable on broad areas such as energy conversion, environmental sustainability, catalysts, and electronic devices. At the same time, the development of functional nanomaterials has been focused on the synthesis, characterization, and potential applications based on their functionality. Hence, there have been developments in highly functional nanomaterials over the past decades through taking their dimension, morphology, size, composition, defect structure, interface, and composite structure as the key factor to regulate the material characteristics (functionality and reactivity).

In this Special Issue on “Functional Nanomaterials: Structure, Properties, and Applications”, we highlight and discuss the recent trends and developments of synthesis, property, and characterization of nanomaterials.

The scope of this issue can be expanded from the synthesis and design of functional nanomaterials to their fabrication, property, and application, which would benefit academia and industry as well. Specifically, this Special Issue will focus on functional materials with specific electrical, thermal, magnetic, chemical, or electrochemical properties as a foundation for designing and fabricating new, desired materials enabling high performance energy storage/conversion or electronic devices. Different synthesis procedures, characterization techniques, and applications for these functional materials will be covered, and novel insights can be proposed.

Potential topics include but are not limited to:

  • Synthesis of nanomaterials
  • Organic/inorganic nanocomposite
  • Energy storage/conversion materials
  • Electronic devices
  • Catalysts

It is my pleasure to invite you to submit a manuscript to this Themed Issue to provide an excellent opportunity for publishing your latest advances in the relevant research fields. Submissions of communications, full papers, and reviews are all welcome.

Based on a fundamental study about the materials and in-depth understanding of the structure–property–application relationship, we anticipate this Special Issue could serve as a certain guiding role for the study of functional nanomaterials or nanocomposites and stimulate a broader range of studies as well, leading to significant progress in this area.

It is well known that ultraviolet (UV) and blue light cause a series of health problems and damages to polymer materials. Therefore, there are increasing demands for UV-blue light-shielding. Herein, a new type of iron-doped titania (Fe-TiO2) nanoparticle was synthesized. Fe-TiO2 nanoparticles with small particle size (ca. 10 nm) are composed of anatase and brookite. The iron element is incorporated into the lattice of titania and forms a hematite phase (α-Fe2O3). The iron doping imparted full-band UV and blue light absorption to Fe-TiO2 nanoparticles, and greatly suppressed the photocatalytic activity. The prepared Fe-TiO2/polyurethane (PU) films exhibited prominent UV-blue light-shielding performance and high transparency, which showed great potential in light-shielding fields. Full article

Ni/(R2O3,CaO) Nanocomposites Produced by the Exsolution of R1.5Ca0.5NiO4 Nickelates (R = Nd, Sm, Eu): Rare Earth Effect on the Catalytic Performance in the Dry Reforming and Partial Oxidation of Methane

In order to clarify the role of R2O3 in the metal-oxide catalysts derived from complex oxide precursors, a series of R1.5Ca0.5NiO4 (R = Nd, Sm, Eu) complex oxides was obtained. A significant systematic increase in the orthorhombic distortion of the R1.5Ca0.5NiO4 structure (K2NiF4 type, Cmce) from Nd to Eu correlates with a corresponding decrease in their ionic radii. A reduction of R1.5Ca0.5NiO4 in the Ar/H2 gas mixture at 800 °C causes a formation of dense agglomerates of CaO and R2O3 coated with spherical 25–30 nm particles of Ni metal. The size of metal particles and oxide agglomerates is similar in all Ni/(R2O3,CaO) composites in the study. Their morphology is rather similar to the products of redox exsolution obtained by the partial reduction of complex oxides. All obtained composites demonstrated a significant catalytic activity in the dry reforming (DRM) and partial oxidation (POM) of methane at 700–800 °C. A systematic decrease in the DRM catalytic activity of composites from Nd to Eu could be attributed to the basicity reduction of R2O3 components of the composite catalysts. The maximum CH4 conversion in POM reaction was observed for Ni/(Sm2O3,CaO), while the maximum selectivity was demonstrated by Nd2O3-based composite. The possible reasons for the observed difference are discussed. Full article

We investigated the flash light sintering process to effectively reduce electrical resistance in silver nanowire networks. The optimum condition of the flash light sintering process reduces the electrical resistance by ~20%, while the effect of the conventional thermal annealing processes is rather limited for silver nanowire networks. After flash light sintering, the morphology of the junction between the silver nanowires changes to a mixed-phase structure of the two individual nanowires. This facile and fast process for silver nanowire welding could be highly advantageous to the mass production of silver nanowire networks. Full article
