Facile synthesis, characterization and electrochemical properties of cuspate deltoid CoO crystallites

Single phase Bunsenite NiO nanoparticles green synthesis by Agathosma betulina natural extract

“…But the major ongoing research focus on nanoscaled NiO is related mainly to its super-capacitor singular applications. Its competitors are ruthenium oxide based nano-systems which exhibit a high experimental specific capacitance varying from 720 to 760 F/g [14][15] yet limited in terms of commercialization due to their elevated cost and toxic nature [30][31][32][33][34][35]. Considering its theoretical specific capacitance which is about 2584 F/g, the synthesis of stable NiO particles with diameter smaller than 20 nm is eagerly researched.…”

Polypyrrole/MnO2 composites and their enhanced electrochemical capacitance

“…For example, transition metal oxides such as hydrous RuO 2 , NiO, CoOx, and MnO 2 have been studied and implemented as electrode materials for ECs. Although they have wide charge–discharge potential range, most of the transition metal oxides have relatively low specific capacity 10–15. Comparatively, conducting polymers such as polyaniline and polypyrrole (PPY) show high specific capacitance, but the relatively low mechanical stability and cycle life are major limitations for applications 16–19.…”

Microstructure and optical absorption properties of Au-dispersed CoO thin films

“…CoO and its compounds have been investigated in many areas because of their exceptionally physical and chemical properties. In the area of electric apparatus, Yu et al [14] studied the capacitance capacity of CoO crystallites prepared by means of developing Co 3 O 4 nanoplatelets in the molten salt and Dhage et al [15] discussed the influence of an alkali earth (Ba/Sr) element in small quantities on non-linear electrical properties of SnO 2 ·CoO·Ta 2 O 5 ceramic. In the application of heterogeneous catalysis, EI-Shobaky et al [16] under a reduced pressure and found the catalytic activity of the CoO powders in the oxidation of CO. Okamoto et al [17] investigated the effects of the starting cobalt salt on the cobalt-alumina interaction modes and cobalt dispersion in CoO/Al 2 O 3 catalysts.…”
