Special Issue Information

Dear Colleagues,

In the last several years, environmental issues related to energy production and consumption and increasing energy demand have become a central point in governments’ concerns. The environmental issues directly related to energy production and consumption include air pollution, climate change, water pollution, thermal pollution, and solid waste disposal. New sustainable technologies supported by advanced materials are a necessity for renewable energy harvesting, storage, and transport. In this view, ceramic materials play an essential role in developing improved or new technologies based on the electrochemical, piezoelectric, or thermoelectric conversion of energy among others, and for insulating applications and emission control. This Special Issue aims to provide selected contributions on advances in the design, synthesis, characterization, and improved properties of advanced ceramic materials for energy-related applications.

Potential topics include, but are not limited to:

  • Design strategies for advanced ceramic materials;
  • Processing of ceramics for energy applications;
  • Characterization methods for advanced ceramic materials;
  • Ceramics for energy storage applications: solid-state batteries, capacitors, supercapacitors;
  • Ceramics for energy conversion: solid oxide fuel cells, piezoelectric ceramics for energy-harvesting devices, thermoelectric ceramics for solid-state energy conversion;
  • Ceramics for high-temperature heat exchangers;
  • Ceramic turbine blades;
  • Ceramics for emission control.

In this study, we synthesized cobalt sulfide (CoS) nanostructures for supercapacitor applications via a one-step hydrothermal method. The effect of hydrothermal temperature on the synthesis process was investigated at temperatures ranging from 160 °C to 220 °C. The structural, morphological, and elemental analyses were performed using X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), and scanning electron microscopy (SEM). The XRD patterns show the hexagonal phase of CoS, and the samples prepared at 200 °C have high crystallinity. The samples prepared at other temperatures show amorphousness at lower 2-theta angles. EDX indicated that the sample was of high purity, except that the sample prepared at 220 °C had an additional oxygen peak, indicating that sulfur is not stable at high temperatures. In addition, a cobalt oxide (CoO) peak is also observed in the XRD data of the sample prepared at 220 °C. SEM images show that the particles in the samples prepared at 160 °C and 180 °C are agglomerated due to the high surface energy, whereas the samples prepared at 200 °C and 220 °C have a distinct morphology. Electrochemical analyses such as cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and galvanostatic charge–discharge (GCD) were performed on all samples. The CoS sample prepared at 200 °C exhibited a high specific capacitance (Csp) of 1583 F/g at a current density of 1 A/g, with low resistivity and high cycling stability. Full article
