We are delighted to announce that article submission to the Special Issue on “Functional materials: from synthesis to applications” is currently open until 15 March 2020. Please find below a brief summary of the scope of this publication:
The rapid development of industrialization and overpopulation is leading to a fast depletion of the natural resources, a growing energy demand, and shortage of fresh water. Therefore, the development of alternative energies, recycle of materials, and wastewater treatment is required to achieve sustainability in our modern society. In order to meet these demands, the search for new materials has become one of the main research topics of Chemistry. The studied materials are usually called functional, in the sense that they have some practical utility derived from their properties in solid state. Such materials have acquired a prominent position in several high-tech areas. For instance, perovskites are widely used for photocatalysis, photovoltaic energy conversion, non-volatile RAM memories, SOFC, superconducting coils, and magnetocaloric devices.
The scope of this Special Issue on “Functional Materials: from Synthesis to Applications” is the synthesis and characterization of transition metal oxides and related materials, which are important for various applications, such as catalysis, photoreforming, wastewater treatment, and production of clean energy. Magnetic, ferroelectric, multiferroic, and superconducting materials are of special interest for the development of more efficient and novel devices.
We look forward to receiving your contributions.

Abstract: In this work we study the electrochemical oxidation (EO) of methyl red, a dye present in textile industrial effluents, selected as model for the degradation of Contaminant of Emerging Concern. The influence of the initial pollutant concentration (1-5 mg dm-3), applied current density (2-15 mA cm-2) and the coupling of ultraviolet (photo-EO) or ultrasound radiation (sono-EO) have been studied using a titanium plate as anode. The results show that EO is able to efficiently remove methyl red and the process efficiency increases with the initial pollutant concentration. Otherwise, it decreases at higher applied current densities due to a less effective mass transfer of the pollutant to the anodic surface. The coupling of ultrasound or ultraviolet radiation entails an antagonistic effect on the process efficiency, due to an excessive formation of oxidants followed by a further recombination process. The anode oxidation produces TiO2-anatase nanoparticles during EO experiments increasing the efficiency of the mineralization process compared to that obtained in a single photocatalysis experiment using TiO2-anatase.
Keywords: Wastewater treatment, electrochemical oxidation, contaminants of emerging concern, photo-electrochemical oxidation, sono-electrochemical oxidation, photocatalysis.
