Special Issue Information

Dear Colleagues,

Driven by the growing demand for carbon neutrality, advanced functional materials serve as pivotal facilitators for the creation of sustainable energy technologies due to their tunable physicochemical properties and structural adaptability. This Special Issue showcases cutting-edge advancements in the design, synthesis, characterization, and application of functional materials for use in addressing the critical challenges facing both energy storage (e.g., dielectric capacitors, solid-state batteries, supercapacitors, fuel cells) and conversion (e.g., electrocatalytic CO2 conversion, sensors, actuators) systems. Contributions from interdisciplinary fields, including computational modeling and simulation, machine learning, chemistry, materials science, and environmental engineering, among others, are encouraged to accelerate the innovation and development of sustainable energy solutions. The scope of this Special Issue encompasses a broad range of advanced functional materials, spanning from dielectrics, piezoelectrics, thermoelectrics, and ferroelectrics for energy storage and conversion to those enabling the achievement of energy efficiency, carbon capture/utilization, hydrogen production, environmental remediation, and beyond.

We invite authors to submit their original full research papers, communications, and review articles to this Special Issue, with the aim of fostering a collaborative exploration of the role advanced functional materials play in propelling the development of sustainable energy storage and conversion technologies.

In this work, the electrochemical behavior of potassium jarosite-type solid solutions synthesized via a controlled hydrothermal method was evaluated. Structural characterization by X-ray diffraction (XRD) confirmed the formation of potassium jarosite. FTIR spectra complemented these findings, revealing bands characteristic of Fe–O metal coordination (625 and 505 cm−1). Voltammetric tests evidenced redox processes attributable to the Fe3+/Fe2+ couple, suggesting that iron within the jarosite framework contributes electrochemically to the observed conductivity. The assembled galvanic cells demonstrated the capability for electrical energy microgeneration, and the presence of jarosite was found to enhance ionic transport within the system. Overall, these results suggest an intergranular ionic-conduction mechanism, possibly facilitated by the mineral matrix, which would act as a structural medium enabling the mobility of charged species.
