“…Supercapacitors, characterized by high power density and excellent cycling stability, have evolved into an important class of new-type energy storage devices [4][5][6]. Electrolyte and electrode material are fairly critical to the performance of a supercapacitor, which makes their research and development become a hot issue [7][8][9]. In contrast to organic electrolytes, mild aqueous electrolytes have merits of high ionic conductivity, nontoxic, safety, non-corrosiveness and convenient assembly in air http://dx.doi.org/10.1016/j.apenergy.2016.06.057 0306-2619/Ó 2016 Elsevier Ltd.

“…5 However, the high cost of Ru has limited its commercial acceptance as an electrode material in electrochemical capacitors. ), [12][13][14][15][16][17][18][19] it emerges that Co 3 O 4 is particularly attractive as an electrode material owing to its very high theoretical capacitance (ca. [6][7][8] But, due to the poor electrical conductivity and poor cyclic stability, the usage of MnO 2 is still restricted, though using a suitably matched redox couple in the aqueous electrolyte its performance could be improved.…”

In recent times, a great deal of attention has been paid to the balanced design and fabrication of core-shell heterostructures for enhanced pseudocapacitor (SC) performance. In this paper, we report the synthesis of ZnO@Co3O4 based core-shell heterostructures with controllable shell thickness for the first time by a simple low-temperature solution-based method and their detailed electrode performance as SC wherein a highly enhanced pseudocapacitance of 296 C g(-1) at a current density of 0.5 A g(-1) has been observed. Further, modifying the surface of ZnO by its sulfur analogue (i.e., by creating a ZnO/ZnS heterostructure), an improved capacitance of 317 C g(-1) at a current density of 0.5 A g(-1) for ZnO/ZnS@Co3O4 has been obtained along with a better rate performance. This is attributed to an efficient charge transfer from ZnS to ZnO. Impressively, the core-double shell heterostructure exhibits high energy density of 36 Wh kg(-1) at a power density of 204.3 W kg(-1). Even at a very high power density of 10.9 kW kg(-1), it shows an energy density of 14.7 Wh kg(-1). To the best of our knowledge, this is the first study of the electrochemical properties of ZnO/ZnS@Co3O4 heterostructure.

“…It is well known that TNT supercapacitors are a type of double-layer capacitors, where a large surface area corresponds to an excellent areal specific capacitance [128–131]. Therefore, enhancing the NT surface area is considered to be an effective approach to improve the capacitance, and numerous research efforts have been dedicated to it.…”

Review of Water-Assisted Crystallization for TiO2 Nanotubes

TiO2 nanotubes (TNTs) have drawn tremendous attention owing to their unique architectural and physical properties. Anodizing of titanium foil has proven to be the most efficient method to fabricate well-aligned TNTs, which, however, usually produces amorphous TNTs and needs further thermal annealing. Recently, a water-assisted crystallization strategy has been proposed and investigated by both science and engineering communities. This method is very efficient and energy saving, and it circumvents the drawbacks of thermal sintering approach. In this paper, we review the recent research progress in this kind of low-temperature crystallization approach. Here, various synthetic methods are summarized, and the mechanisms of the amorphous–crystalline transformation are analyzed. The fundamental properties and applications of the low-temperature products are also discussed. Furthermore, it is proved that the water-assisted crystallization approach is not only applicable to TNTs but also to crystallizing other metal oxides.
