“…Zhang and others reported that the hydrogen bond formed could be associated with the molecular packing in the solid state (Yao et al, 2015;Oh et al, 2016). Further, Du and Hu's research group reported that thin film with good packing or crystallinity is beneficial for charge carrier mobility (Hu et al, 2000;Zhang et al, 2017Zhang et al, , 2018Du et al, 2018;Muhammad et al, 2020). Hence, the small ABDF molecule has been used in organic field-effect transistors with high performance, as reported by our group .…”

High selectivity and sensitivity detection of fluoride anions (F − ) in an organic solution by the naked eye has always been a challenge. In this investigation, a simple compound based on aminobenzodifuranone (ABDF) was designed and synthesized. Deprotonation of the amino moiety caused by F − is responsible for a color change from dark blue to various colors (colorless, yellow, orange, and red) in different common organic solvents due to a blue shift over 200 nm in the UV/Vis spectrum. The color change is quite visible to the naked eye under ambient light. The detection limit for F − can reach a concentration of as low as 5.0 × 10 −7 M with high selectivity, even in a solution containing multiple anions.

“…From combined Z ″ and M ″ plots, the mismatch between Z ″ and M ″ peaks indicates the charge carrier migration are not mainly long range, and the short‐range movements also exist in dielectric response process. In order to understand the mechanism of HTDR and ion conduction, we can calculate the relaxation activation energy ( E a ) and conductance activation energy ( E c ) by Arrhenius equations [35–37]:

τ = τ_{0} \cdot \exp ()(, E_{a} / k_{β} T)

σ = ω ε_{0} ε_{r} \tan δ

σ = σ_{0} \cdot \exp ()(, - E_{c} / k_{β} T)

Advanced materials and technologies for supercapacitors used in energy conversion and storage: a review

et al. 2020

View full text Add to dashboard Cite

Supercapacitors are increasingly used for energy conversion and storage systems in sustainable nanotechnologies. Graphite is a conventional electrode utilized in Li-ion-based batteries, yet its specific capacitance of 372 mA h g −1 is not adequate for supercapacitor applications. Interest in supercapacitors is due to their high-energy capacity, storage for a shorter period and longer lifetime. This review compares the following materials used to fabricate supercapacitors: spinel ferrites, e.g., MFe 2 O 4 , MMoO 4 and MCo 2 O 4 where M denotes a transition metal ion; perovskite oxides; transition metals sulfides; carbon materials; and conducting polymers. The application window of perovskite can be controlled by cations in sublattice sites. Cations increase the specific capacitance because cations possess large orbital valence electrons which grow the oxygen vacancies. Electrodes made of transition metal sulfides, e.g., ZnCo 2 S 4 , display a high specific capacitance of 1269 F g −1 , which is four times higher than those of transition metals oxides, e.g., Zn-Co ferrite, of 296 F g −1. This is explained by the low charge-transfer resistance and the high ion diffusion rate of transition metals sulfides. Composites made of magnetic oxides or transition metal sulfides with conducting polymers or carbon materials have the highest capacitance activity and cyclic stability. This is attributed to oxygen and sulfur active sites which foster electrolyte penetration during cycling, and, in turn, create new active sites.
